A Few Details About New Streetcars

Based on some of the comments here as well as a few of my own interests, I recently posed three questions to the TTC about the new Bombardier cars.

1. What are the “specified options” mentioned in the report, and when will we know which of these, if any, will actually be included in the order?

Specified options include security camera system, wheel flange lubrication, pantograph current collector, cab training simulator etc. 

Timing for ordering optional equipment depends on:

  • better definition of scope of work and system offered (e.g. camera system);
  • technical and noise necessity (e.g. flange lubricator);
  • system compatibility (e.g. pantograph); and,
  • completion of negotiation of the design and scope of work (e.g. cab simulator).

 2. When will a plan showing the interior layout be available which accurately reflects the dimensions of the Toronto car? Will there be an opportunity to fine tune this, or will that be done as part of the prototype operation when there’s a real car for people to walk around in? I have to assume this must already be available for discussions with ACAT.

While the exterior dimensions are fairly well set, the interior layout can be an evolving process. As noted at the April 27, 2009 Commission Meeting, there are four cost-neutral layouts that would afford flexibility in the final configuration. The current schedule calls for completion of the Conceptual Design Phase four (4) months after Notice of Award (NOA); Preliminary Design Phase twelve (12) months after NOA.

There will be opportunities to review the design through computer modeling and presentations during the design phases. A full-scale, half-car mock-up is scheduled for delivery in 18 months NOA. This would offer a “real car” feel for stake holders including ACAT to critique. The actual Prototype Car No. 1 is scheduled for delivery 26 months [after] NOA.

3. For the transit city network, will this be built to TTC gauge or to standard gauge? In other words, will the two systems and fleets be physically able to interoperate (assuming the TC cars stay away from “tricky” parts of the legacy network) or will the two systems remain disjoint?

This has a specific application to the St. Clair line because there has been talk of connecting it to Jane and operating it out of a TC carhouse. This would require that the 512’s trackage be made compatible with the TC fleet. This has obvious and immediate implications if the specs for the TC fleet have to be nailed down within the next year.

The Transit City network will be built to TTC gauge. Note that once the carbody structure, bogies, articulations etc. of the legacy system vehicles are proven through design, Finite Element Analyses, testing and validation, there will be savings in “proven” equipment and configuration for the TC vehicles, as well as savings through common tooling, manufacturing and quality control processes, if negotiation with the base vehicle carbuilder is successful.

TTC’s wider gauge also offers a wider aisle width and roomier interior, with little incremental construction cost, compared with a “standard gauge” vehicle.

Interoperability obviously involves more than track gauge. If Jane cars are required to operate on St. Clair, a whole host of challenges will have to be addressed, including tight radius curves and steep grades at St. Clair West station and short turn loops en route.

 Thanks to Brad Ross, Director, Corporate Communications at the TTC for this information.

After receiving Brad’s reply, it occurs to me that if St. Clair cars are to be based at a TC carhouse via Jane Street, this would be done by keeping some “city” cars at the new Eglinton West carhouse and running them over the TC network down to St. Clair.  This assumes, of course, that the Jane line is on the surface and makes a physical connection with an extended 512.  All of that is many years in the future, and St. Clair cars will be based at downtown carhouses for many years to come.

Who Will Pay for New Streetcars?

A great deal of bilge was pumped out by Ottawa and Queen’s Park over the past few days about the TTC’s proposed order of new streetcars from Bombardier.

In today’s Globe & Mail, John Barber did a particularly nice job of eviscerating George Smitherman, the Minister of Infrastructure, for his apparent total ignorance of the TTC’s funding needs and requests.

It’s no secret that the TTC is looking for new streetcars.  The original bid process had to be halted when no vendor came up with a technically and commercially compliant proposal, and more recently the whole process of getting a second set of bids has been well covered in the media.

Many of us will remember walking through Bombardier’s mockup display at Dundas Square which happens to be in Smitherman’s riding.  Maybe he was out of town at the time and missed it.

Smitherman claims that the City can’t make up its mind what its priorities are.  Strange that in a letter to Dalton McGuinty, copied to Smitherman, dated December 16, 2008, Mayor Miller wrote of upcoming meetings of Finance and First Ministers:

Toronto’s first priority for infrastructure is to build Transit City, the 21st century modern public transit network that our city needs.  The Government of Ontario has demonstrated foresight and leadership in its support for Transit City.  Toronto City Council has unanimously agreed to request the Government of Canada to provide:

  • $368 million toward the streetcar fleet’s replacement and expansion; and
  • the federal $6 billion share of Ontario’s $17.5 billion Move Ontario 2020 commitment for the Metrolinx Regional Transportation Plan.

The streetcar fleet replacement also shows up in the list of funding requests under the stimulus program by the Federation of Canadian Municipalities.

Other related letters to both Queen’s Park and Ottawa can be found on the City’s website.

Meanwhile, Smitherman’s comment that the TTC shouldn’t be awarding a contract without knowing funding is in place shows that he is badly out of touch.  First off, the TTC has not signed the contract, and its execution is dependent on funding being in place.

Second, there is a long history of agencies such as Metrolinx (a provincial body) announcing plans for which they have no funding, and for which even discussion of proper funding won’t happen for years into the future.  There are two subway extensions (Spadina/Vaughan and Richmond Hill) of which the first was not fully funded until long after the project was announced, and the second still does not have full commitments.

That’s how projects like this work.

The streetcar purchase will run over a 10-year period, and funding it can hardly be called a short-term stimulus.  Funding would likely come from some other program, but the funding should come.  Toronto is asking, in effect, for $40-million a year from Ottawa and from Queen’s Park to re-equip the core of central Toronto’s transit system and to anchor the expansion of LRT in our city.

Bombardier Recommended for Low Floor Streetcar Order (Updated)

Updated April 25, 9:30 am.  I have added material from the media briefing and the staff report that I did not have time to incorporate in the original article.  The additional material is appended below after the break. 

On April 24, the TTC announced that Bombardier has won the competition for an order for 204 new low floor streetcars for Toronto.  The staff recommendation will go to the Commission itself for approval on Monday, April 27.

Both Bombardier and Siemens bid on this tender, and the proposals from both vendors were considered to be compliant both on technical and financial grounds.  Therefore the question came down to cost and with Siemens’ bid over 50% higher than Bombardier’s, there was no question about the winner.

The vehicles will be a modified version of the Flexity car with three powered two-axle trucks and five car sections.  Bombardier has not yet updated their site with information about the vehicles (as of 2:00 pm EDT April 24).  An illustration of the proposed car is in the Toronto Star’s article posted earlier today.

Although not guaranteed, this contract places Bombardier at the front of the line for supplying cars to the much larger Transit City system, especially if that builds out to anything near its full extent.  The contract includes provision for add-on orders, but the TTC will be negotiating their price separately as the Transit City cars will have significant differences affecting their cost:

  • Transit City will be built to specifications that allow off-the-shelf cars to operate on it — no tight curves or steep grades.
  • The TC cars will be double-ended and double-sided.
  • The TC cars will likely have only two powered trucks rather than three.

Subject to funding, a process still under negotiation with the Federal and Provincial governments, the first prototypes would arrive in Toronto in mid-to-late 2011 for non-revenue testing.  Production deliveries would start in 2012 and stretch out to 2018 by which time the last of the existing CLRV and ALRV fleets would have been retired.  A new carhouse, likely in the Port Lands, will be required to house this fleet while the older cars would run from Russell and Roncesvalles.

Postscript:  I cannot help mentioning that the illustration of the new car shows a vehicle facing westbound on Queen at Bay signed “Neville”. Continue reading →

Trolley Buses? Not For Toronto (Update 2)

The TTC commissioned a report from Dr. Richard Soberman on the economics of trolley bus operation in Toronto.   Cutting to the chase, the conclusion is that creating a new system from scratch is uneconomic, and we should wait for coming improvements in electric vehicles.

Soberman’s report makes a strong case against trolley buses on its basic economic arguments, and that’s a debate worth having.  However, electric vehicles have yet to make a substantial dent in the personal car market, let alone for vehicles the size of a city bus.

I have one simple reply:  Remember CNG?  The saviour of the enviroment for the TTC?  We lost the old system through neglect and through belief in an unproven technology, not to mention political machinations.

For your reading pleasure:

Commission report and summary

Dr. Soberman’s report

Updated February 15:

A detailed review has been added to this post.  Some of the document is reasonably accurate, but there are enough outright mistakes and misdirections to cast the whole thing in an unsavoury light.  This is a report that tries to sound balanced while hoping we won’t notice what it gets wrong either by accident or by design.

Update 2, February 16: My long-time Vancouver friend Angus McIntyre pointed out two issues with the Soberman report.

  • Vancouver will order an additional 34 articulated trolley buses funded from the Federal gas tax.  This adds to the new fleet of 188 standard and 40 articulated buses.  These plans are not reflected in the TTC report even though the press release is over a month old.
  • The substation spacing of 1.5 to 2km is a measure used on “feederless” systems such as Seattle’s where small local stations feed directly into the contact wires rather than the Toronto or Vancouver model with large substations feeding a local network of services.  Has the report used Seattle’s close spacing, but Toronto’s costs for larger substations?

Buses on Streetcar Routes?

The CBC this morning carried an item reporting that the TTC would begin running buses on streetcar routes to relieve crowding.  Chair Adam Giambrone was quoted as saying that cars don’t get out of the yard due to “safety” problems such as dashboard heaters failing and causing windows to fog up.

Sigh.  That’s this week’s excuse.  Things are getting bad when the best that Giambrone can trot out is that chestnut “safety” that is a catch-all excuse in the same league as “congestion” and “TTC culture”.  The real problem is that the TTC has been hiding reliability problems with the streetcar fleet for years, and needed service improvements don’t show up because they don’t have enough working cars.  The problem has been masked because at least one carline has been under construction for most of the last five years.

Next week, a new schedule comes into play on Queen with less, yes less service than today.  The reason?  The operators need even more layover time (strangely only on weekday schedules but not in the evening), and the TTC comes up with this by stretching the headways.

Management’s refusal to undertake a restructuring of the line, to break it into separate components that don’t have an immense round trip and a corresponding need for layovers, is getting quite trying.  The use of relief crews at Russell Division works in the east end because the carhouse is near the end of the line, but a completely different scheme is needed in the west for Long Branch bound cars.

If we are going to start busing streetcar lines, then let’s stop running inadequate service to handle the demand on the routes.  Stop telling us about average loads that are within standards when news reports include clips of people complaining about huge gaps and crowded cars.

Thanks to inaction on streetcar reliability, riders will have to put up with ongoing problems for three years until the new fleet begins to arrive.  Even that is dependent on funding, and I am not convinced that the streetcar fleet will survive the many demands for new money in Ottawa and Queen’s Park.  Is this the beginning of the end?  A fate like the trolleybus network that was allowed to deteriorate beyond the point of no return?

Better Batteries for Hybrid Buses

The TTC’s supplementary agenda for this week includes a report on the settlement of negotiations with Daimler for the problems with the hybrid bus fleet.  Parts of this report are confidential, but the main items of interest for system users are in the public report.

  • The existing fleet of hybrid buses will be converted from lead acid to Lithium-Ion batteries.  This is expected to greatly improve reliability and to reduce fuel consumption by about five percent due to the much lower weight (4,100 vs 1,000 pounds) of the batteries.  (The TTC quotes the weight in pounds.)
  • The 2009 bus order for 130 hybrids will remain in place.
  • The optional 2010 bus order for 120 diesels will proceed.  It should be noted that supplementary Federal funding for “green” bus technology is not guaranteed into 2010.
  • Due to the larger than expected number of vehicles required both for construction projects (e.g. St. Clair) and to compensate for poor hybrid reliability, 52 “retirement-eligible” GM buses will undergo a life extension.  This is expected to add 2 to 3 years to their life.  Buses now out of service will be the first to go through this rebuild so that the active fleet is not further depleted.  This project will cost $3.5-million or about $65K per bus. 

From a budgetary point of view, the total spending remains below the original Capital Budget mainly due to the savings on diesel versus hybrids on the 2010 bus order.

Transit City — The Movie

Today’s TTC meeting brought us an update on the various parts of the Transit City plan.  You can read the full report yourself, and there is a quick review of the status of various lines and studies below.

Meanwhile, the TTC is starting a media campaign to tell people about Transit City and about LRT.  You can watch the video on the TTC’s website.  Although it is a breath of fresh air to see the TTC promoting LRT after all these years, there are a few oddities in this piece (the timings where they occur are included below).

  • (0:39) “Work on Transiy City is already well underway.”  Hmmm … a few traffic barriers does not make a construction project.  I wonder why they don’t show the upheaval on St. Clair?  Shortly later we see a new car mockup superimposed on the westbound stop at Yonge Street.
  • (0:55)  “What is Light Rail Transit?”  We learn that LRT is used around the world including, wait for it, in Vancouver!  Er, ah, there’s a heritage streetcar line running with a former BC Electric interurban car, but no LRT.  This is a howling error.  Other cities shown on the world map are many fewer than the actual inventory.
  • (1:15)  “LRT can operate in a street, but has the flexibility to operate underground like a subway.”  LRT advocates will be amused to hear that their chosen mode has the “flexibility” to be just like a subway, when the real issue is the inflexibility and cost of 100% grade separated modes.
  • (1:50) Light rail is bigger than standard streetcars, and allows level boarding from platforms.  It’s nice to hear how LRT is a streetcar, but not a streetcar.
  • (2:10) LRT cars don’t need loops!  Amazing what you can do with modern technology.  See also Kennedy Station Loop.
  • (2:20) All door loading … but wait .. it’s a subway car!
  • (2:38) LRT will be separated from the effects of traffic congestion, not to mention pesky “transit priority” signals if the animation can be believed.
  • (3:32) Streetscaping.  Aside from the gigantic, fast-growing trees (maybe they’re from Vancouver too), note the typical suburban layout with wide setbacks of buildings from the street.  Contrast this with later illustrations of dense suburban redevelopment.
  • (4:05) Transit will be an even better travel alternative.  With a new subway train?  What’s that doing here?

The map of projects reflects the original Transit City announcement because many possible changes are still under study by both TTC and Metrolinx.

Transit City project updates follow the break.

Diesels, Not Hybrids, At Least For Now (Updated)

Updated October 23:  The TTC amended the staff recommendations by adding two clauses, roughly as follows:

  • The TTC should withhold award of the optional 120-bus add-on order for clean diesels with Daimler Buses until the problem with batteries on the existing fleet are resolved.  If this is not done, the TTC should go with an alternative supplier.
  • The TTC should investigate conversion of the 2009 bus puchase from Hybrid to Clean Diesel.  Staff should explore the options for contract termination as well as the impact of the technology change on funding from various sources.

It is unclear how the first point can be achieved given that the cutoff date for exercising the existing contract’s add-on provision is October 31, 2008.

At this point it is clear that the 2010 bus order will be diesel, and there is a strong move to convert the 2009 order as well notwithstanding possible advances in battery technology.

The Economics of Hybrid Buses

The City of Toronto’s Executive Committee agenda for October X contains a report on the City’s Green Fleet Plan for various agencies.  By far the biggest of these is the TTC, and in an accompanying report, we learn just what the economics of the hybrid bus fleet are.

On page 15, the TTC presents a chart showing the fuel efficiency of its fleets, and it is worth noting that fuel consumption per vehicle km is rising at the same time as the average capacity of the vehicles is falling.  This is partly due to the additional systems, notably air conditioning, that are present on newer vehicles.

Of the total fleet, just over a quarter (450 out of 1653) are hybrids, and these consume about 10 percent less fuel than their pure-diesel cousins (based on experience to date).  This implies that the increased fuel consumption on the diesel fleet is even higher, proportionately, than the consolidated figures imply because of the offsetting benefit of the hybrids.

In the longer term, the relative fuel savings of hybrids may rise as they operate on routes with dense, stop-start traffic where the benefit of electric propulsion and battery energy storage will shine.  Nonetheless, there will be a considerable net cost of owning hybrid buses relative to diesels over their lifespan.

The TTC expects to spend $110-million on diesel fuel in 2009.  This includes a saving of $3.6-million for the existing hybrid fleet, and that saving will rise to somewhere around $6-million annually by the time that the fleet is about 50% hybrid (854 out of 1864) in 2011.  That’s a per vehicle saving of  about $7,000 per year.  We do not know yet what savings, if any, on maintenance will accrue to the hybrid fleet.

The capital cost premium for a hybrid bus is about $200,000, and the hybrid saving is only about 3.5% per year on this additional investment.  In time, if the capital cost premium comes down, the cost of fuel goes up, or the average percentage saving across the fleet rises, the numbers will converge and the rate of return will improve.

Meanwhile, it’s a shame we don’t have comparative figures for the cost of trolleybus infrastructure for our major routes.  Two decades ago, the TTC sacrificed its trolleybus system on the twin altars of environmental responsibility and natural gas buses.

Postscript:  The supposed economic advantage of natural gas as a fuel was almost entirely due to the fact that it was not taxed.  A large chunk of the TTC’s annual fuel bill is in tax paid to the Province of Ontario.  Without this tax, the economics of buses in general would be rather different.  Oddly, because the dollar saving from reduced fuel consumption would actually be lower without the tax, the economics of hybrid buses would look even worse if this tax were rescinded.
