Old Wine in New Bottles?

Since September 2025, the TTC CEO’s Report has included a new presentation of various performance stats both to improve clarity, and to allow a deeper dive into each mode – subway, bus, streetcar – than was done in past reports.

This article presents the new pages for surface modes side-by-side, followed by the subway versions which differ because of the operating environment and infrastructure.

It would be heartwarming to see a revised set of data, but my gut feeling is that the new format adds little to older reports than pulling together many stats for each mode in one place. The actual content still leaves a lot to be desired.

To be fair to the TTC, there is a project underway to review and improve the KPIs [Key Performance Indicators] used to monitor the system, but this is not yet reflected in the reported data.

A pervasive problem with TTC’s self-monitoring is that many statistics are averages over long time periods, locations and routes. There is no sense of local variability or “hot spots” deserving of attention. Use of averages hides the problems, and prevents exception monitoring to show whether improvement happens where it is really needed.

Other metrics allow management to present a rosy picture when this does not match what riders actually see and politicians responsible for transit hear about in regular complaints.

Some metrics are demonstrably invented out of thin air. I have already written about how, until September 2025, bus reliability stats were artificially capped making eBuses appear much more competitive than they actually are. These stats should be restated for previous years to show actual trends, not fairy tales about bus reliability.

Short turns are under-reported by an order of magnitude, and the percentage of short trips is much higher than the numbers reported by management.

Crowding is reported on the basis of “full” or “crowded” status, but these are not defined, nor is there any recognition that the approved Service Standard for off-peak is different than for peak vehicles. What might be considered only “crowded” in the peak would be well beyond the off-peak standard.

Recently, the average speed of streetcars was misrepresented as being strongly affected by autos blocking the tracks when, in fact, the lion’s share of these incidents were the result of the winter snowstorm and the ineffectual clearing of roadways by the City of Toronto. Traffic obstacles for streetcars (and in some cases for buses) remains a problem, but misrepresentation of stats will only undermine calls for better transit priority.

Fleet availability is reported relative to scheduled service, but without any discussion of factors that could limit how much service the TTC attempts to operate. This includes operator shortages through budget limits. A basic metric for transit fleets is the “spare ratio”, the number of spare vehicles above and beyond regular service requirements. Some spares exist for routine maintenance, some for ad hoc service, but some are simply sitting with nothing to do because there is no budget for them nor for the operators needed to better utilize the available fleet.

A related question is the degree to which a high spare ratio reduces the effect of vehicle failures because the pool available for scheduled service is so high. A high number of spares represents both a capital cost (procurement and yard capacity) and an operating cost (routine maintenance). Does the high number of spares represent real availability for better service, or are these the duds left on the sideline except for extreme emergencies? How large is the truly available fleet for each mode?

“On time performance” is a misleading term on several counts.

  • The metric has historically only applied to terminal departures, not to overall route behaviour.
  • A separate headway metric is now coming into use, and it is much more generous for the divergence of actual from scheduled service than the on-time metric in most cases.
  • Service Standards define metrics for early arrivals and for missed trips, but these are not reported.
  • Delay logs report the length of a service blockage/diversion, but give no indication of the number of vehicles or riders affected.

With the continued reporting of ridership levels today compared to pre-pandemic times, what is missed is a comparison of service levels. Leaving aside the bunching & gapping issue, service on most streetcar routes is less frequent, sometimes dramatically so, than it was in early 2020 and before. The wider headways are compounded by bunching problems which accentuate the relative infrequency of scheduled service. Decades ago, we saw how 501 Queen lost a substantial portion of its ridership when longer ALRVs replaced CLRVs on comparably wider headways. How much of the current ridership loss is due to much less attractive service as opposed to some inherent weakness in demand?

A comparison of pre- and post-pandemic service levels is at the end of this article.

The remainder of this article reviews the charts in detail.

Bunching & Gapping: AI To The Rescue?

In a previous article, I examined the report on the Bunching & Gapping pilot now in progress at the TTC.

At the November 3 Board meeting, there was almost no discussion of that report, but in its place management provided a short presentation. Unfortunately, this portion of the meeting was not uploaded to YouTube, and so readers will not be able to view it for greater detail.

Information about hot spots on routes was presented in a different way from the original report. Both versions are shown below.

The original version has more granularity showing the issues specific to each route segment.

The presentation shown at the meeting included a hot spots map across the whole system, but this is not included in the published deck. I will ask TTC for a copy and add it here when available.

The important point about that map is that the hot spots are all over the city, while conventional wisdom presents this more as a downtown, streetcar-centric problem.

Results on the pilot routes have been mixed, and even this has required a high level of supervision that likely would not scale to the entire system and most hours of service. As an alternative, the TTC is considering an AI (Artificial Intelligence) tool developed at York University. Initially this would be used in an advisory manner to route supervisors who would decide whether its recommendations were valid. Later, it would directly instruct operators to hold enroute to even out headways.

A decision to hold a vehicle would take into account the relative loads of the leading (gap) bus and the trailing (bunched) one. Ideally, a bunched bus will have the lighter load and holding it to space service will affect fewer riders. This is not always the case if pairs of buses leap-frog to share the work along a route, and the “trailing” bus might have the heavier load at some points.

A proof of concept dashboard gives an idea of what might be presented to a route supervisor. This shows recommended holds, as well as the distribution of historical and predicted bunching. Note that the scale on the chart is the number of bunched buses, not the gap size to be corrected.

The challenge here will be for the AI model to predict future behaviour. Many things affect bus spacing, and some of them are not predictable. For example, irregular terminal departures can begin a process where a small gap gradually widens. That effect can be predicted and service adjusted, but the actual late or early departure is only known when it happens. Developing gaps are easy to spot along a route because the future service at a location can be predicted by what is in the few kilometres approaching it.

Congestion caused by accidents cannot be predicted, but the act of smoothing out service can deal with its results at least in part based on past experience with similar events. There is no mention of short turns or tracking of issues with buses running late due to insufficient schedule time, or the timidity of a junior operator.

Notable in the presentation is the implication of headway management, not on-time performance. The TTC needs to decide which of these it will adopt and incorporate that into terminal dispatching.

There is also the question of whether the Service Standards are too generous in defining the allowable variation in “on-time” and “headway” values. Departures are supposed to be no more than 5 minutes late, and never early. Headways on a 10-minute service like 7 Bathurst can vary from 5 to 15 minutes. If the AI tool uses these as its goal, it will perpetuate the uneven service allowed by the standards, particularly in headway management. There is also a danger that route speed will be determined by spacing service to accommodate the slowest drivers.

No computer system inherently “knows” what it is supposed to achieve, and depends on the parameters set down by its developers. If the TTC does not fully understand what “good service” should look like, an AI tool will only work toward expectations built into its design. An important component should be the ability to tighten or relax the targets for “good” service management.

TTC plans to shift the focus of its more intense supervision from the 7 Bathurst and 24/924 Victoria Park routes to 29/929 Dufferin and 25/925 Don Mills. I have collected tracking data on these routes for some time, and will publish analyses of changes in route behaviour after a few months have accumulated.

The Board approved the following motion:

Request TTC staff report back to the TTC’s Strategic Planning Committee as a part of consideration for 2026 budget priorities on the resource requirements, staffing, and operational needs to sustain a full-year Bunching and Gapping Pilot in 2026 as well as the feasibility of expanding the pilot to additional key routes across the City to improve service and reliability.

The next meeting of the Strategic Planning Committee is on November 25, 2025.

The UITP Peer Review of TTC Rail Systems

In September 2025, I reported that the UITP (International Union of Public Transport) had delivered its peer review of TTC rail systems, but that TTC management did not want this document in public.

See: The UITP Peer Review: What is the TTC Trying to Hide?

A decision on whether to release the document was put off until the November 3, 2025 Board meeting, and partly redacted documents were released on November 5. See:

Very little of the report or response is redacted, and the sections withheld are listed as containing “information about the security of the property of the local board”. At one point as the report made its way through previous debates, “commercial confidentiality” was also cited, but that has disappeared in the version that was released.

The management responses lie in three separate documents, with most items being “accepted and in progress” or “pending further assessment and potential resourcing”. Some of these will require participation by groups outside of the TTC, notably City Transportation Services. I will leave it to readers to peruse the responses linked above.

Readers should note that this is not a general review of TTC operating and maintenance practices, but rather a discussion of how the TTC keeps track of maintenance needs and manages its fleet and infrastructure. Only a few operating practices come in for comment. This review only covers rail modes, and the report is silent on bus operations and maintenance.

Subway vehicles and Streetcar vehicles are the main elements in the scope of this peer review. Other related subsystems like power, track, overhead catenary and signaling systems, which are essential parts for the operation of Subway and Streetcars,2 have been reviewed as requested by the TTC.

This peer review is a strategic review of the asset management plan and maintenance processes and is not a technical analysis nor assessment of the systems within the scope apart from the review of the Automatic train control (ATC) system specially requested by the TTC.

The aim of this peer review is to assess the TTC asset management plan and some other relevant documents, to identify gaps and improvement areas in line with the best international practices and standards. [p. 12]

Although the UITP team reviewed the TTC’s practices both through virtual discussions and information exchange, and through on-site visits, some comments give the impression that the team did not pick up on all of the local details.

Some TTC practices are lauded including the degree of in-house expertise and avoidance of outsourcing. This is ironic considering the ongoing efforts in past years to shift work to the private sector. The UITP review is quite clear in favouring the in-house option.

It is noted that the TTC conducts much of its maintenance in-house. It is good practice to keep maintenance of most systems, including rolling stock, signaling and track, in-house in order to maintain technical and performance knowledge within the organization. Whilst outsourcing may seem an attractive proposition, as it leaves the responsibility for the process to another party, it will be more expensive, and it removes control of the maintenance processes from the operator.

The long lifespan of many railway assets means that changes will take place as a result of experience in operation and maintenance processes. There will be modifications to equipment to improve reliability or reduce maintenance requirements. The life cycle of the asset is better managed by the operator if the operator has full knowledge of the performance of the asset. A maintenance contractor will take that knowledge from the operator and reduce their ability to monitor cost effective life cycle processes. [p. 18]

The bulk of the review and recommendations lie in Section 7 running from page 16-46. This article will sketch the key points, and interested readers should refer to the full report.

The items are presented mostly in the order that they appear in the document. Some sections give the sense that the authors attempted to review the TTC in detail, while others have a “cut and paste” feel of general suggestions with little reference to the Toronto situation, or the city’s position relative to other major transit systems.

TTC Misrepresents Growth in Streetcar Delays from Blocked Tracks

At the TTC Board meeting on November 3, management presented statistics on streetcar delays broken down by type of incident. TTC is quite fond of portraying external incidents, especially those related to congestion, as the root of (almost) all evil. The following page is from the CEO’s Report.

Note that external delays (turquoise) occupy the majority of the chart. During discussion of the problem of autos fouling rails, a passing remark by the Interim Chief Operating Officer piqued my curiosity when he said that there were many delays due to the winter storm.

This sent me to the TTC’s delay statistics which are available on the City’s Open Data site. There are codes for many types of delay including “MTAFR”, short for “Auto Fouling Rails”.

According to the “In Focus” box above there has been a 400% year-over-year increase in these delays, although they are styled as “fowling” implying a flock of chickens might be responsible for service issues.

Sorting the data by code and summarizing by date produces interesting results.

  • Between January 1 and September 30, 2025, there were 843 MTAFR events logged.
  • Of these, 586 fall between February 14 and 26 hitting a daily high of 65 on February 17.

These blockages were not caused by the typical traffic congestion, but by the City’s utter failure to clear snow on key streets.

  • 105 were on 501 Queen
  • 42 were on 503 Kingston Rd.
  • 84 were on 504 King
  • 93 were on 505 Dundas
  • 186 were on 506 Carlton
  • 3 were on 507 Long Branch
  • 1 was on 508 Lake Shore
  • 2 were on 509 Harbourfront
  • None were on 510 Spadina or 511 Bathurst
  • 6 were on 512 St. Clair
  • A few dozen were on various night cars

The pattern here is quite clear: routes on wide roads or rights-of-way were not seriously affected, but routes on regular 4-lane streets were hammered. (How 511 Bathurst was spared is a mystery. At the time it was running with streetcars from Bathurst Station to King & Spadina, and with buses on the south end of the route.)

To claim that the 400% increase from 2024 is some indication of worsening traffic problems is gross misrepresentation of what actually happened. Although this is the CEO’s report and he almost certainly did not assemble the information himself, he wears this issue for having reported misleading data to the Board and public.

Direct comparison with published 2024 data is difficult because until 2025 the TTC used a much coarser set of delay codes that lumped many types of events under generic headings. There was a category “Held by” in which there were 625 incidents from January to September in 2024. The 843 MTAFR codes in 2025 are quite clearly not a 400% increase over 2024.

Whenever there is a discussion of unreliable service, we hear endlessly about traffic congestion. This definitely is a problem, but not the only one, and certainly not in the way presented by the CEO.

A question arose during the debate about the problem that performance stats are consolidated across all routes. Route-by-route service quality is presented in detail in the second part of this article for all streetcar routes. This shows that problems are widespread in the system, even on routes with reserved lanes.

As for the delay stats cited by the CEO, it is clear that we are not comparing September 2025 to one year earlier as the text implies, but using events from the entire year to date including a major snowstorm that had no equivalent a year earlier. The so-called 400% jump in delays from blocked tracks is due to snow and poor road clearance by the City.

TTC management owes the Board and the public an apology for blatant misrepresentation of the delay statistics.

TTC Bunching and Gapping Pilot

The TTC has a pilot program underway on several routes with increased supervision in an attempt to improve service quality by addressing service gaps and bunching. These are complementary effects in that a gap is often followed by a bunch, although gaps can also occur due to missing vehicles and short turns. See:

The pilot evolved over the year as some of the challenges and resource needs to manage service became apparent.

March 2025Pilot launched on 7 Bathurst, 24 Victoria Park, 924 Victoria Park Express, 25 Don Mills, 925 Don Mills Express, 29 Dufferin, 929 Dufferin Express, 100 Flemington Park, 165 Weston Road North, 506 Carlton, 512 St Clair.
Dedicated staff to manage each route were not used initially and results were poor.
June 2025The pilot was scaled back to 7 Bathurst, 24 Victoria Park, 924 Victoria Park Express, 506 Carlton, and 512 St Clair.
One route supervisor was assigned to each route.
September 2025100 Flemingdon Park and 165 Weston Road North were added.
October 2025Pilot “refined” to focus on the weekday peak periods.

The TTC recognizes that delays leading to gaps can be caused by several effects: “including including Operator behaviour, customer incidents, traffic congestion, city events, construction, and operational factors, such as door/ramp operations.” [p. 2]

Later in the report, there is mention of the effect of passenger loads and long traffic signal wait times.

If vehicles are crowded either because service is inadequate for demand, or because a gap creates an extra load, they will take longer at stops. Filling vehicles to the brim can be counter-productive and inefficient. Space limitations onboard can delay passenger movement especially for those with large objects (e.g. strollers, luggage) and mobility devices. Although ramp operations are mentioned, there are many other types of passengers with extra space and boarding time needs.

Transit signal priority is also mentioned, but there is no indication of where or what priority measures were added on the pilot routes.

The remainder of this article reviews the metrics used by the TTC to track the success of the pilot project, as well as problems and actions that might be taken to resolve them.

TTC Annual Network Plan 2026

At its November 3, 2025 meeting, the TTC Board will consider management’s proposed 2026 Network Plan. This is a very long set of documents, and this article will only cover the major points. Readers wishing more detail should refer to the reports.

The recommendations are quite simple:

  • Approve the 2026 plan and associated network changes, and
  • Forward the plan to City Councillors, sundry senior City officials, and the General Managers of various regional transit agencies.

The “key themes” of the plan are cited as enhancing connections to meet customer needs, reviewing the express bus network and planning for construction. The “enhanced connections” are very small scale, the express review will be in next year’s plan, and construction plans are not unlike what we saw for major projects in 2025.

Running in parallel with the Network Plan is work on a Ridership Growth Strategy “which is a cost-benefit analysis of service, fare, infrastructure, and customer experience initiatives aimed at increasing ridership, pending funding.” [Main report, p. 2] This exercise, like the Network Plan, too often is budget constrained, and that mindset, including the concept that if only TTC were more businesslike, financial problems would dwindle if not vanish completely.

The Ridership Growth Strategy has yet to appear even as a consultative proposal. There is no sense of the TTC’s ambitions and whether the “strategy” will consist of the lowest possible cost changes under the guise of making the system more attractive. In an election year when keeping taxes down is a political priority, bold schemes for transit spending are hard to find.

The concept of “cost-benefit” too often ignores the general economic worth of having a transit system in the first place. There is a deep gorge between capital megaprojects where a very high multiplier effect is claimed for investment in infrastructure, and operating expenses which are treated as a burden on the City and its funding partners. Calls for fare supports and better service are treated as irresponsible demands on the public purse, but billions spent so commuters can travel hither and yon across the region are not seen as a waste. Nobody ever asks subway advocates how we are supposed to pay for their dreams.

One part of the 2026 plan reviews “poor performing routes”, but past experience shows that this generally nibbles around the edges of financial problems while giving the impression of a hard-nosed review. It does not address questions of service capacity, latent demand and quality which, after all, should be primary concerns of any transit system.

At the same time, the plan claims to have a focus on social goods:

The 2026 ANP builds on the 5YSP [5 Year Service Plan], which continues to highlight the importance of equitable, reliable, safe, and timely access to transit for the three key priority groups: women, shift workers, and lower-income customers.

Many initiatives proposed in the 2026 ANP address travel patterns of the key priority groups who continue to depend on the transit network for getting around the city. [Main Report, p. 2]

The TTC cannot be both a penny-pinching, “efficient” business while also serving goals that may not, at least on the TTC’s books, be cost-effective. Arguments that efficiencies will help pay for better service miss a key point: there are already major problems with transit service affecting all riders, and they will not be fixed by cuts to a handful of minor routes.

The TTC serves everyone, not just “key priority groups”. Indeed it is strong demand from a wide range of riders that justifies good service, provides revenue to help fund it and generates political support for further improvements.

The reference to “many initiatives” is misleading. Few changes are proposed, and they are small scale.

Consultations with a wide variety of groups including politicians, community groups, day-to-day riders, special needs riders, transit advocates and transit operators revealed consistent complaints across the city about crowding, service reliability and the accuracy of public information. These are not issues just for a few squeaky wheels, advocates who are dismissed as having too much time on their hands to criticize transit, but for ordinary riders everywhere.

A favourite buzzword, “innovation” makes its appearance in an attempt to justify ongoing work:

A more efficient and customer-friendly TTC network encourages more people to choose transit, helping reduce car dependency, lower emissions in support of the City’s ransformTO Net Zero Strategy, and making better use of existing fleet and infrastructure.

The 2026 ANP will support ongoing and future planning processes that leverage innovation, particularly in enhancing ridership data analysis as well as monitoring and reporting KPIs. A key focus will be continued improvements in how route and system productivity is measured through data-driven decision-making.

Additionally, this plan supports the TTC’s transition to a zero-emissions network by making scheduling adjustments to accommodate the deployment of eBuses across the network. [Main Report, pp 3-4]

Customer friendliness and better data analysis are not “innovations” except for an organization that has forgotten its primary mission. As for scheduling adjustments for eBus deployment, this is actually a new cost because of the lower range of battery buses, a cost, not a benefit, of “innovation”.

The plan argues that it prepares “the network for long-term growth … by aligning with the TTC’s commitment to building a resilient, competitive, and sustainable transit system.” [Main Rport, p. 4] That will not happen with small scale route changes, budget-constrained service improvements, and an attitude to reliability that sees the primary obstacles as outside of the TTC, notably traffic congestion. Yes, that is a problem, but it is too conveniently cited while ignoring basics of scheduling and line management.

The plan cites 2026 budget costs of only $0.6 million for implementation of proposed changes. This is very small change. A further $13.2 million (net) is proposed to roll out service changes approved in the 2023 and 2024 plans, but not yet implemented. There is no sense of when these would occur and how much new service would actually operate in calendar 2026.

A further problem is that there is no reference to the cost of restoring service to levels set by the board-approved Service Standards for crowding. Although the TTC has trip level crowding data, system performance is reported on an aggregate, all-day basis giving a far-too rosy picture of actual conditions riders encounter. Honest, granular reporting of service quality is an “innovation” long overdue.

TTC Headway Reliability on Small Routes (Part II)

This post continues from Part I, and is broken off from it simply in the interest of keeping each article a reasonable size. For introductory comments please see Part I.

Routes included here are:

65 Parliament
70 O’Connor
72 Pape
75 Sherbourne
83 Jones
87 Cosburn
88 South Leaside

91 Woodbine
92 Woodbine South
111 East Mall
112 West Mall
114 Queens Quay East
154 Curran Hall
168 Symington

Problems seen on many routes in Part I show up here as well including:

  • Less reliable service on evenings and weekends
  • Missed trips due to missing buses without an attempt to rebalance headways to eliminate wide gaps

Most readers are only interested in some of the routes here, and that is why I have only published a few charts per route with links to details in PDF sets. Only the truly keen (some might say obsessed) and, of course, those whose job it is to know these details will look at just about everything.

Apologies if I’ve missed your route. I plan to look at others once the Line 5 and 6 changes fully cut in to see how new service designs work.

To those who ask why I publish so many of these route analyses, the answer is, sadly, that it takes a lot of data to make the point that erratic service is not found on only a few routes, nor only on major city-spanning bus and streetcar routes. “Traffic congestion” is too simplistic an explanation too often raised by the TTC, and it simply does not apply in some times and locations where these routes have poor service. TTC has no metric to report on this problem, and therefore no tracking mechanism to flag issues or the result of corrective strategies, if any.

King/Dufferin Reopening / Better 505 Dundas and 511 Bathurst Service Soon

The City of Toronto has announced that work at King & Dufferin is finished and the intersection will reopen to traffic on Wednesday, October 29 after 7pm.

Regular service will be restored on 29/929/329 Dufferin, and the 503 Kingston Road bus will be extended west from Joe Shuster Way (east of Dufferin) to Roncesvalles at 5am on Thursday, October 30.

TTC will test the new track and overhead during the week of November 3 and will restore 504 King and 508 Lake Shore services from their current Shaw/Queen diversion when the intersection is cleared for streetcar operation.

Meanwhile, the TTC CEO’s Report notes that six minute or better service will come to 505 Dundas and 511 Bathurst from 7am-7pm 7 days/week starting November 16.

Ontario Announces Testing Complete for Finch West LRT

The 30-day Revenue Service Demonstration for the Finch West LRT is complete, and the TTC will take full operational control of the line no later than Monday, November 3, 2025 according to an announcement by the Ontario Ministry of Transportation. A date for revenue service will be decided by the TTC.

The next planned schedule changes for the TTC are on Sunday, November 17, and Sunday, December 22, 2025. Implementation of any changes for November 17 are already well underway internally, and it would be a stretch to see route 6 Finch enter revenue service that soon unless the TTC had already made provision for this. Service change details for November 17 are not yet public, but should start to emerge both from internal sources and from the posting of new online schedule data used by trip planning apps in early November.

The announcement notes that the Eglinton Crosstown line is currently going through its own demonstration period, but the status of that testing has likely been affected by a collision in the Mount Dennis yard as reported by the Toronto Star.

Also announced are:

  • November 16, 2025: Opening of Mount Dennis GO/UP Station as well as the passageway under Eglinton Avenue at Eglinton West station to reduce pedestrian crossings at the surface.
  • The Crosstown stations at Mount Dennis and Eglinton West will not open until revenue service begins on the line, and at that time Eglinton West will make the long-planned name change to “Cedarvale”.

The Ministry touts various changes made based on experience with the Crosstown project that were applied to the Finch project and others:

  • Using simpler, proven signal and power systems from other LRT projects to reduce design complexity and technical risk, making delivery, testing and commissioning smoother.
  • Working collaboratively with building partners to identify critical funding for testing and commissioning and ensuring claims and legal barriers do not impact this process.
  • Onboarding the maintenance provider earlier in the process to ensure the fleet and line are ready for service sooner.

It is not clear what “other LRT projects” might have more complex signal and power systems, but Eglinton is unique in the amount of underground running where trains will be under automatic operation. Problems with premature brake wear on the Flexity LRVs used on Eglinton were traced to incompatibility between the automatic train control system and the braking system on the cars causing them to brake too strongly. This has been corrected, but considering the years the line has been under construction and testing, it is amazing that this problem was only recently found and dealt with.

The points about working collaboratively with “partners” building the line and bringing a maintenance provider “onboard” earlier speak to basic flaws in project design and contract management. A passing reference to the Eglinton line “which began construction under the previous government in 2011” tries to fob off responsibility for issues with Metrolinx that the Ford government had years to correct.

This article will be updated as more information becomes available.

TTC Seeks Consultant for Streetcar Overhead Engineering

The TTC has an open RFP on the Bonfire site for a Triennial Contract for design services for its streetcar overhead contact system. Much of this document is boilerplate legalese, but the scope of work shows that the TTC plans to address key issues with systems related to streetcar overhead. Five specific tasks are listed in the RFP and more might be added over the term of the contract.

  • Overhead/Traction Power Supply Study
    • This involves a review of the existing system that supplies power to streetcars and the demands placed on it as vehicles move through the network. There is no mention of modelling the effect of increasing service, but this should obviously be part of the study to determine where constraints might exist to service growth. (The recent suspension of streetcar service on Bathurst during the busy CNE period thanks to a power supply failure is an obvious incentive for this work.)
  • Overhead Design for Interections
    • This task would review existing intersections with a view to improvements where appropriate.
  • Overhead Design for New and Existing Lines
    • The title is self-explanatory but it begs the question of why a new design is needed for the existing system, much of which has been rebuilt once for dual-mode trolley pole and pantograph operation, and again for a pantograph-only configuration. The latter work is still in progress, and is responsible for some of the extended bus-streetcar substitutions in recent years. Also notable is the absence of any reference to eBus charging infrastructure.
  • Streetcar Track Switch
    • Although track switches are not part of the power supply to streetcars, historically they were controlled through hardware mounted on the overhead wires. The current system uses antennae in the pavement and on streetcars, and responsibility for the system rests with the Streetcar Overhead section.
  • Streetcar Signal System Alterations
    • The definition of this task is unclear in that there are almost no signals anywhere on the streetcar system. Moreover, there is no reference to the interface between streetcar operations and traffic signals.

In this article I will address only the last two items as they are both related to issues of streetcar operating speeds, a topic raised in a recent UITP review of the streetcar system. (See The UITP Peer Review: What is the TTC Trying to Hide?) Details from this review might become public at the November TTC Board meeting.
