Union Loop: Trading One Bad Design For Another? (Update 1)

 

I have received a drawing of Union Station Loop that shows its end-state configuration including provision for all services.  This drawing is different from the version in the Queen’s Quay Revitalization document in (a) showing the full length of the west platform and (b) clarifying the staging of implementation for different routes.

The orange section is the first phase to expand capacity onto two platforms.  The pink section would be added to serve the Port Lands development, and the blue section for Bremner.  In its final configuration, according to the TTC:

The currently-proposed layout would ultimately have all of the service to and from the east on the platform under the east teamway allowing us to run two routes/branches from the east, one of which could be a 60m train. Service to and from the west would load under the west teamway with a Queens Quay route (509 or 510, not both) loading on the northern-most platform and the Bremner service loading on the southern-most platform. All of the platforms would operate independently from each other allowing flexibility for service management.

Original Post from March 29:

In my enthusiasm for the new Queen’s Quay designs, I neglected to look carefully at the current scheme for Union Station Loop, especially in the context of plans to build the expanded loop in stages.

Back in the days when the existing loop was designed, Philip Webb and I had a rather testy meeting with TTC Engineering about the capacity of this loop.  Outrageous claims were made for its ability to handle riders even though the TTC (a) completely missed the loss of platform space to carbody swingout and (b) assumed the full capacity of the corridor would be available for passenger flow rather than being used for stacking space as it is today.  The loop is and has been for some time grossly inadequate, and it is a monument to the TTC’s pig-headedness.

Queen’s Quay Revitalization Plan

This week, Waterfront Toronto released detailed plans (18MB download) for the redesign of Queen’s Quay between Bathurst and Parliament Streets.

Updated May 7, 2009:  The presentation has moved to a new URL, and related information can be found on the project’s web page.

This plan is the culmination of several studies, some of which seemed to go on forever, but in the end we have a design that has widespread community acceptance.  By “we”, I mean Toronto, my city, a city that too often settles for half-baked functional plans that do little to stir real pride in what we have and what will be built.

Some elements of this plan have appeared on this site before, notably the design work for the East Bayfront LRT and the long debates on a portal to the Bay Street LRT tunnel.  I will try not to duplicate those details.

This post is intended as an overview of the long presentation, a walking tour, if you will, along the waterfront-to-be.  Page numbers refer to the PDF itself regardless of any numbers that may appear on individual panels. Continue reading →

All Over The Waterfront (Update 4)

Update 1, March 17, 5:50 pm:  More details have been added about the various alignment options for the Waterfront West line through Parkdale.

Update 2, March 24, 7:55 pm:  Feedback from the TTC about Parkdale alignment details.  Details of Queen’s Quay public meetings added.

Update 3, March 25, 6:00 am:  The preferred option for the Kingston Road line is BRT.

Update 4, March 28, 11:10 pm:  The presentation from the March 25 public meeting on the Queen’s Quay redesign is now available online.  Note that this file is almost 18MB for those of you with slow network links.  The document is quite extensive, and I will review it in a separate post.

Transit planning on Toronto’s waterfront leaves much to be desired thanks to the patchwork of overlapping studies and projects for two decades.  Options for the portion between Parkdale and Bathurst Street have changed with the recent cancellation of the Front Street Extension, but no planning based on ths possibility has ever been conducted.

Throughout its history, planning for the waterfront has been fragmented and compromised to fit around whatever other projects had real political clout.  To help focus discussion of the waterfront as a whole, this post gives an overview of all of the projects and schemes from Long Branch to West Hill.

Waterfront East Surfaces At Last (Update 1)

Update 1, March 5:

The presentation materials from the CLC meeting on March 2 (discussed below) are now available online.  (Warning: 7.5MB file)

On March 2, I attended what is likely the final meeting of the Community Liaison Committee (CLC) for the Waterfront East LRT project.  Further discussion of this subject will now be consolidated with the Queen’s Quay redesign project.

The primary outstanding issue from our discussions going back a few years was the location and number of portals from the Bay Street tunnel to the eastern branch of the Harbourfront route.  Options involving a swing west into Harbour Street, down York Street or down Yonge Street were rejected in an earlier round as being impractical for various reasons involving available space and gradients needed to reach the surface within available city blocks.

Five options were studied in detail, of which one will be the recommended option going forward.  These options were:

  • Bay Street between Lake Shore and Harbour.  Under this option, the existing west portal and Queen’s Quay Station would be abandoned, and a new common surface stop would be created on Bay north of Queen’s Quay.  This option is physically constructible, but poses serious operational problems due to congestion of pedestrians, road and LRT traffic at the Bay & Queen’s Quay intersection.
  • Bay Street between Queen’s Quay and Harbour.  This option will not fit, physically, in the space available.  There is not enough room for tracks to rise to the surface to a “landing” before the special work for a surface intersection with Queen’s Quay.
  • Queen’s Quay between Bay and Yonge Streets.  In this option the portal would lie east of Bay and the stop would be just east of Yonge.  This scheme poses many problems because the road is constrained on both sides by existing buildings.  Access to these buildings, as well as the continuity of pedestrian and cycling areas planned for the street would be difficult or impossible.  This scheme is not viable.
  • Queen’s Quay between Yonge and Freeland Streets.  In this option, the line runs in tunnel to Yonge and then rises to street level just west of Freeland.  The station would be just east of Freeland.  This area has enough room to allow the Queen’s Quay design to be continued through the portal area, and has no adverse traffic impacts.  The Toronto Star building north of the proposed portal has no ground level retail that would be injured by the portal’s presence, and any new building on the south side can be designed for its environment.  This is the recommended option.
  • Queen’s Quay between Freeland and Cooper Streets.  In this option, the line would run in tunnel including an underground station at Yonge, and would rise in a portal in front of the Queen’s Quay LCBO.  The first surface stop would be near Jarvis Street.  This option was rejected primarily because of cost.

Initially, the line will be ended in a temporary loop near Parliament Street at a location to be determined.  A separate study is reviewing the redesign of the Don Mouth area including connection of the Cherry Street LRT through to hook up with the Queen’s Quay East line.

Construction of the new tunnel east from Bay will include modification of the existing structure under the intersection at Queen’s Quay so that a full “T” junction including a through east-west track can be installed.  This would allow a direct service linking the western and eastern waterfronts and on through to the Distillery District or the Port Lands.

The TTC also discussed the expansion of Union Station Loop, but their design has not changed noticeably for over a year.  Some fine tuning is required to bring their scheme into alignment with the proposed Union Station redevelopment plan and its new retail and GO concourses.

The first meeting of the consolidated LRT and Queen’s Quay Design CLCs will occur on March 11, and I expect to have more details on the overall scheme for the line in the larger context of the Queen’s Quay redesign project.

There will be a public drop in centre for these projects on Saturday March 28.  The final version of the Environmental Assessment for the Queen’s Quay East line will go to the TTC in May and to Council in July.  Assuming funding, the line would likely begin operating roughly in 2013.

I will post links to relevant documents as they appear online, as well as details of the drop in centre on March 28.

Coming Soon

The past few weeks have been rather quiet for news, and I, along with half of Toronto, have been getting over a bad cold that dampened my enthusiasm for writing.

Very little of substance happened at the February TTC and Metrolinx meetings, and that’s why there was virtually nothing here about them.

Recently, I received the vehicle monitoring data for Queen and related routes for the months of December 2008 and January 2009, and I have just started to work on formatting it for analysis and comment.  This period includes some truly appalling weather, as well as different approaches to line management.  It also brings GPS location to the route (most of the time, most of the vehicles), and this has required some programming changes in the analysis software.  (The data are still quirky, but in a different way.)

I hope to start publishing articles based on these new data in a week or two.

Meanwhile, work by Waterfront Toronto and TTC on the Queen’s Quay east line has surfaced after a long hiatus, and I hope to report on updated plans for this project soon.

Transit City Status Update

This month’s TTC agenda includes a long update on the status of the Transit City plans.  I will not attempt to précis this report, but will touch on points of particular interest.

Funding is in place to allow continued work on Environmental Assessments [sic] and other engineering work, but the real challenge comes later this year when construction is slated to begin on Sheppard.  The fog may clear a bit once the provincial budget is announced and we know just how much money will flow to Metrolinx and to transit in general.

A related problem, of course, is the question of new LRVs for the existing and future streetcar/LRT networks.  By the time the budget is out, the TTC should know what the bids for new cars look like, and Queen’s Park will have to decide whether they are serious about paying for them.

Scarborough RT/LRT Benefits Case Analysis (Updated)

Updated February 3:  In a previous version of this post, I was using 4-car trains for the Base Case and therefore claimed that the fleet was undersized.  This has been corrected.

On January 16, the Metrolinx Board approved release of the Benefits Case Analysis (BCA) for the replacement and extension of the Scarborough RT.  This document is now available online.

The original TTC proposal, was simply to replace the current technology with Mark II RT cars on the existing alignment. This is now referred to as the “Base Case”.  Four alternatives, all considered superior to the base case, were evaluated in the BCA.

  • 1: Extend the RT 5.4 km to Malvern Town Centre using the current technology.
  • 2: Extend the RT to Markham & Sheppard where it would connect with the Sheppard East LRT including an LRT branch north to Malvern.
  • 3: Replace the RT over its entire length with LRT and extend to Malvern on approximately the same alignment as the first RT option, completely in an exclusive right-of-way.
  • 4: Replace the RT with LRT and extend to Malvern with a partially exclusive right-of-way east of McCowan.

Major Flaws in the BCA

To save readers from combing through the rest of the text, here are major points where the analysis does not hold up.

  • The peak demand for which the line is designed, 10K/hour, is substantially above the modelled peak demand of 6.4K/hour in The Big Move.  The Metrolinx regional plan includes frequent commuter rail services through the extended RT’s catchment area, and this likely attracts some riders away from the RT.  Designing for higher capacity than required inflates fleet, carhouse and operating costs.  It may also affect train lengths and the cost of retrofitting existing stations.
  • LRT options presume the construction of a dedicated carhouse for the Scarborough line even though, by the time an LRT would operate, the Sheppard line’s new carhouse would be operating and could act as the base for Scarborough trains.  This inflates the capital cost of LRT options.
  • The alleged cost-benefit ratios are highly sensitive to the presumed value of travellers’ time.  This value is orders of magnitude greater than the value of environmental effects (reduced car use) and dominates the calculations.  The model overall favours proposals that serve long trips at comparatively high speeds (e.g. with widely spaced stations) that may not be conducive to the type of neighbourhood preferred in the Official Plan.
  • The values assigned to savings from reduced automobile use are based on a much higher factor than in the VIVA Benefits Case report, 95 vs 23 cents per km (2031).  The effect is to grossly overstate the savings from reduced auto usage for all options.
  • Economic benefits include the money spent on labour during construction.  This value for all options is a disconcertingly low percentage of the total project cost (well under 20%).  This shows that a substantial portion of any scheme is consumed by planning and design, materials, vehicles and system component costs.  Moreover, the idea that spending more on one project is “good” because it generates more work is valid only if one ignores other projects that could be built with the same money and labour.  This will be an important factor when projects are weighed against each other.
  • Estimates for the length of time the RT would be closed for upgrade or restructuring are “at least 8 months” for RT and “up to 36 months” for LRT.  These figures need to be reviewed in detail to determine where the differences lie.  The numbers are taken from the original TTC study (which did not include the qualifiers) when the physical changes needed to handle Mark II RT cars were considered to be trivial.  This may no longer be true.
  • Overall the analysis looks at the RT in isolation from the surrounding network and ignores alternative ways that the demand might be served on the network, not just on the RT corridor.  Although the report shows LRT as the less expensive option, the difference versus RT options may actually be understated.

The Scarborough LRT That Wasn’t (Updated)

Updated January 16:  The Metrolinx board has agreed to publish the Benefits Case Analysis for the SRT replacement project.  As I write this, they don’t have a working website, but once the report is available, I will review it here.

Updated January 11:  John F. Bromley has kindly supplied photos of CLRVs 4000 and 4001 showing the cars with pantographs.

My archives yield up interesting goodies from time to time.  In anticipation of the Benefits Case Analysis report at Metrolinx for the SRT replacement and extension project, I thought it worthwhile to revisit the original Scarborough LRT.

Here’s Progress Report No. 1.

 

Yes, it’s a streetcar!  That was the original plan, and the line was built for CLRVs.  That’s why there is a streetcar-radius curve at Kennedy, and if you look closely, the remnants of clearance markers on the original low platform at track level.  When the station opened, even though it was RT by then, the graphic over the up escalator was a streetcar.

Note the design for the station at STC where the streetcars are at the same level as the buses.  It didn’t take long for someone to hoodwink Scarborough Council into thinking that this simply would not do, and the streetcars needed their own level lest they isolate the land south of the station from development.  Anyone who knows the site knows that the bus roadway does quite a good job of that.

pr2pg5c

By Progress Report No. 2, which is otherwise quite similar to No. 1, the design has changed to an elevated structure.  Moves were already afoot to substitute RT technology, but the streetcar line took the political hit for imposing an elevated on Scarborough’s new Town Centre.

In time, the RT technology replaced the LRT scheme.

A few things worth noting here are that the estimated cost has gone from $108.7-million in the LRT plan to $181-million in the RT plan.  The final cost would actually be in excess of $220-million thanks to add-ons including extra cars.  The CLRV fleet was planned to be 22, and the RT fleet we wound up with is 28.

The RT promo also claims that because the wheels are not used for traction or braking, there will be lower vibration compared with conventional vehicles.  In those days, the CLRVs were still running with the original Bochum wheels, and streetcar track construction guaranteed lots of corrugations and noise.  The RT developed its own problems in time because those wheels do bounce, and they are also used for the final braking effort when they can (and do) slide producing flat spots.

Now, almost 30 years later, we are finally looking at extending the RT further north.  If this is done as LRT, it will be able to share a new carhouse and trackage with the Sheppard East LRT, and will also form the northern portion of the eventual Scarborough-Malvern line.

When the Metrolinx analysis comes out next week, we will see whether the lure of expensive, unnecessary high technology still rules the decision, or whether we can start to undo the damage of building that orphan RT line so many years ago.

Update:  Here is John F. Bromley’s photo of CLRV 4000 fitted with a pantograph at the SIG factory in Neuhausen, Switzerland on June 29, 1977.

Front Street Extension: Going, Going …

This morning, the Planning and Growth Management Committee adopted a report recommending that the Front Street Extension be removed from Toronto’s Official Plan.

Soon, soon, the FSE will be officially dead.

Now if we can only get a sensible look at the Waterfront West LRT line rather than the piecemeal approach of past years.

For the record, I do not agree with schemes to bring transit into downtown via Front Street because this will run into severe problems in front of Union Station where current plans call for considerable increase in pedestrian space.

Where Would a Don Mills Subway Go?

There has been a lot of discussion here about potential alignments for the eastern leg of a downtown relief line.  On occasion I have mentioned a route rather different from the commonly discussed one via Pape, the Leaside Bridge and Overlea, and I am sure this has caused some confusion.

One advantage of having been at this transit advocacy business for a long time is that I have a long memory and archives to match.  For your delectation, here is a proposed route from Don Mills and Eglinton to downtown.  It is a TTC Subway Construction Department drawing dated December 12, 1973.

donmillsalignmentdec73c

A few things worth noting about this drawing:

The route north from Danforth is via Donlands, not Pape.  This provides access to Greenwood yard via the connection shown.  It also aligns the route further east to simplify the valley crossing north of O’Connor.

The route passes through the middle of Thorncliffe Park and proceeds north to Eglinton.  This is more or less the sort of alignment I have been talking about for the east leg of a DRL (or, for that matter, for the Don Mills LRT if it came south of Eglinton).

Two alternative alignments from the CNR line to Queen are shown.  One goes straight south while the other runs along the rail corridor.  Going west along Queen brings its own problems, and these were discussed in an earlier, 1968 report that I will present in a separate post.  (Please don’t clutter up the comments thread here with questions about that part of the alignment.  You will get your chance.)

I present this information mainly so that people can see that the idea of a subway to Eglinton and Don Mills is hardly new, and it’s not even mine — I simply resurrected an old TTC concept.  When we discuss transit plans, it is useful to know some of the history.
