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.

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.

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.

Scarborough-Malvern and Finch West LRT EAs (Update 1)

The first round of public meetings for the Scarborough-Malvern line will be held on July 23rd and 24th.  Meetings for the Finch West line will follow on July 29th, August 6th and 7th.

Scarborough-Malvern Project Site

Finch West Project Site

Updated July 30:  The Scarborough-Malvern display panels are now available online.  Note that on Page 13 the peak ridership forecast is now 4,600 to 5,000 per hour.  This change from earlier estimates (3,900) I reported is due to the incorporation of updated population and employment projections, and the change to 2031 as the reference year to match the estimates in Metrolinx studies.

Various routes from Kingston Road north to Malvern via UofT Scarborough Campus are shown in the display.  The preferred route travels north on Morningside as far as Sheppard, then west (via shared trackage with the Sheppard East LRT), the north via Neilson to Malvern Town Centre.  The alignment would be generally in the middle of roads except possibly near UTSC depending on what design would best serve that campus.

The Finch West site now was a FAQ which gives a projected peak ridership for the line of 2,300 to 2,800 per hour.  The lower figure matches the earlier published 2021 estimate.  I am not sure if the two studies are drawing on the same source of ridership estimates, and I will follow this up with the planners.
