Service Improvements, Someday

Peter Kuitenbrouwer in the National Post has a series of articles talking about crowding on the TTC.

One more person, and this subway’s gonna explode

If you ignore the smell, the bus is still the better way

A seat on the Queen streetcar? Don’t make me laugh

The February 17 service improvements are a start, but it’s no secret that there’s a long way to go. A few changes are in the wind as described in a TTC report from their February 27 meeting.

We learn that more service will come with the March 30 and May 11 schedule periods to address the backlog of overcrowding, at least on the bus routes.

In the fall, further improvements will change the peak hour loading standard for bus routes. Across the board, the standard will be improved by 10% so that the acceptable average loads, now in the mid-50s depending on vehicle type, will be reduced by 5 or 6. This won’t mean 10% more service on every route because some lines are running below the new standard already and won’t be eligible for more service. (These tend to be short routes where cuts today would have a severe impact raising the average load above the line or making the headway unacceptably wide.)

Also planned for the fall is a return to full hours of service on most routes so that if the subway is open, the routes are operating at least a 30-minute service. 2009 may bring a 20-minute maximum, but that’s a budget issue for next year.

Meanwhile, we see little discussion of streetcar or rapid transit service because both suffer from constraints in fleet size. That may be the situation, though I am skeptical, but what is missing is a projection of what we would need if we made the same changes in loading standards for the rail modes. Continue reading →

Interminable Waits at Kennedy (Update 3)

Updated Feb 27, 6:15 pm:

At today’s TTC meeting, we learned that they expect to have repairs at Kennedy completed by Friday. I will post more information about the derailment and the nature of the damage when I receive an electronic copy of the report on this incident.

Correction Feb 26, 11:00 pm:

This evening, I received the following email from Adam Giambrone, Chair of the TTC. It was addressed jointly to me and to Ed Drass whose column I cite later in this post.

Steve,

I told Ed Drass yesterday that I understood the slow order was to be off by now BUT that I was going to check with Warren Bartram of TTC during a tour of the tunnels with CTV earlier this morning (2am-5am) to confirm. I actually watched the crews doing the repairs and I called him earlier today to confirm that the slow order was still in place and will be for another week or so.

The problem is that many of the bolts (I don’t know their technical name) that bolt the rail to ground were ripped up (some 150) and there is only so much that can be repaired in the 150 minutes they have most days to do the work.

Anyway, I usually qualify a statement of fact if I am not sure and I did so in this situation.

Adam Giambrone

I expect to get more details at the TTC meeting tomorrow and will post that info here.

This post has been revised in light of Adam Giambrone’s email.

Updated Feb 26:

This morning at 8:40 am, the backlog of trains from Kennedy stretched to Victoria Park Station, and the trip from there to the terminal took 21 minutes.

According to Ed Drass’ column in today’s Metro, Adam Giambrone was advised that the slow order on Kennedy crossover was lifted last week. This proved to be incorrect based on his email quoted above.

Original post:

Ever since the Kennedy Station derailment two weeks ago, service at the eastern terminal of the Danforth Subway has been glacial, especially at the end of the peak periods. As an example, I spent more than 15 minutes this morning getting from Victoria Park to Kennedy Station, and this has happened almost every day for the past two weeks. Looking on the bright side, the TTC has figured out how to operate a reasonable headway on the SRT even when it was in “manual” mode and we no longer creep from Kennedy to STC. The combination of these two delays made the term “rapid transit” quite a joke.

The problem at Kennedy arises from the slow order which has been on the crossover. Trains move over it at low speed while TTC staff watch carefully as the trains pick their way through the special work. Riding on trains, I can’t tell whether the roughness of the crossing is due to the very slow speed or the condition of the track. With luck, we will learn more at Wednesday’s Commission meeting when there will be a presentation on the derailment.

Meanwhile, capacity on the BD subway is badly constrained. In two previous posts, I talked about the physical limitations that subway line and terminal layouts place on the frequency of service.

How Often Can Subway Trains Run?

How Frequently Can We Run Subway Trains?

The minimum headway at a terminal controls the level of service on the rest of the line unless additional trains are inserted at short-turn points. Indeed, that is how the TTC plans to fit more trains onto the Yonge line in eight years or so with turnbacks at Finch (following a northerly extension beyond Steeles) and somewhere in Downsview (following the York U extension).

Just to review, here is the sequence of events at a terminal:

  • Signal turns green
  • Train guard initiates door closing and this completes
  • Train moves off from platform and eventually clears the crossover
  • Signal system determines that the crossover is clear and realigns the switches
  • Signal system displays clear for the incoming train
  • Incoming train starts up and crosses into the station
  • Signal system determines that the crossover is clear and realigns the switches

The two longest steps in this sequence are the train movements. Today, I timed trains at Kennedy, and it takes 80 seconds for a train to move from a stationary position either on a platform (departing) or from the last approach signal (arriving) through the crossover to a point where the junction is clear for another movement.

This means that 160 seconds (2 minutes, 40 seconds) are consumed simply for train movements. Add to this about 10 seconds for signal and switch system activity, and we are up to 170 seconds before any delays introduced by the readiness of crews to depart.

However, the scheduled headway on the BD line is 144 seconds (2 minutes, 24 seconds) in the morning peak. Quite clearly, it is impossible to operate this headway given the constraints at Kennedy, and a queue of trains builds up. This affects service on the entire line unless trains are inserted along the way to bring the headway back down to the scheduled level.

The TTC should seriously consider short-turning some trains. This could be done at Warden, provided that these trains crossed over to the westbound platform so that they did not block the eastbound flow. Yes, this would require careful management at Warden, but it would reduce the backlog at Kennedy and allow a reliably frequent service to operate on the rest of the line.

I say this with some trepidation because this scheme could also foul up the line just as badly as the current arrangement if it were not managed to ensure fast in, fast out turnarounds of the short-turning trains.

A further option, applicable only to the am peak, would be to send trains that would run out of service to Greenwood into the yard eastbound.

I write this not just as someone who is personally inconvenienced, but out of concern that a long-standing operational problem affecting service capacity has not been addressed.

After Wednesday’s update at the TTC, I will add to this item as appropriate.

Low Technology Has Its Place

This morning I had the dubious pleasure of riding the SRT from Kennedy to STC in what was clearly a manual dispatch mode. Trains were not always at full speed, and each station-to-station move was made after clearance from SRT control.

Much grumbling was heard from passengers around me as this sort of thing is not uncommon in bad weather.

I couldn’t help thinking how the SRT was supposed to be an LRT line originally, and how the capabilities of its ATO system have never been exploited or needed on a line with such infrequent service. As an LRT line, it would have had limited signals at the terminals and for the underpass at Ellesmere, and operation would be “on sight” for most of the route.

I have seen the train control system do wonders with interlined services on the Vancouver SkyTrain where, also, the operation is completely automatic. In Toronto, the signal system just gets in the way, an example of technological overkill.

What Does Building a Subway Cost?

In the previous item here, I wrote about the Metrolinx study tour including a visit to Madrid. A report reviewing that tour was on yesterday’s Metrolinx Board agenda.

The “Madrid Miracle” is always an issue for discussion. How could a city build so much rapid transit so quickly? Part of the answer lies in the political climate where just getting the work done takes priority over endless political posturing, announcements, jurisdictional wrangling and little action. Part of the answer lies in the money lavished on Madrid by other governments. But part is the much lower cost of building subway tunnels in Madrid compared to other cities thereby making subway expansion much more affordable regardless of who pays for it.

The TTC produced a complementary report examining the differences between Madrid and Toronto to determine just where the cost differences lie. The material that follows is a paraphrase from the TTC’s material with a few of my own observations. Continue reading →

Mind the Doors! (Updated)

In today’s Metro, Ed Drass writes about the problem of subway car doors closing before people have a chance to get on and off. (The article is not yet online except in the full PDF version of the paper.)

Updated: This item has been clarified to show that Ed is paraphrasing the TTC’s remarks rather than directly quoting them. My apologies if the earlier version of this piece misrepresented the situation.
Drass paraphrases the TTC as saying:

… the TTC has not changed its policy, but ridership has definitely grown across the system. Train guards are given about 15 seconds at each station, typically opening the doors for shorter periods at quiet stops and longer at busy ones.

When asked why trains wouldn’t take longer at busy stations, the TTC replies:

If you extend it too long you’re going to develop gaps in your service.

Drass notes that the TTC has asked for help with expanding capacity on the subway, but it is unclear from his article whether this is his own comment or a paraphrase from the TTC itself. Such relief, in the form of new trains and signal systems, won’t be here for years and only affects the Yonge line.

Moreover, they won’t address problems with jackrabbit behaviour at stations. Although the TTC worries about keeping the service properly spaced, the signal system (anqituated though it may be) does that today unless, of course, the service is late. Like other TTC systems, it focuses on schedule maintenance, not headways. When trains are late, operators are free to make as brief stops as possible in an attempt to get back on time again.

There is no excuse for ultra-brief station stops, trapping people in trains before they can get off, or catching people in the doors. All have happened to me, and not during the peak of the rush hour when we can blame the problem on rising demand.

Once again, the TTC needs to get its own house in order before blaming those pesky passengers who insist on getting on and off the trains for their problems.

A Visit to the City Archives

Now and then, I spend my time browsing through the photograph collections at the City Archives, and this activity can be rather addictive.  The main page includes a link to a search page where you can start your travels.  Note that the indexing is spotty, and if you find items in a series that you really like, it is often worthwhile drilling down into the linked pages for the specific collections and looking for a “browse” link that will bring up the entire content.  I can’t put links to such pages here as they are built on the fly.

After looking at photos of my old neighbourhood in North Toronto, I stumbled on paintings of the Yonge Subway by the artist, Sigmund Serafin, whose paintings of Bloor and University subway stations are posted at Transit Toronto.  I have recently learned more about Serafin’s history, and that post will be updated in the new year.

I will leave the joy of finding intriguing bits and pieces to you, but there are a number of items I thought worthwhile to whet your appetite. Continue reading →

“One Stop” Doesn’t Stop Here

The video advertising screens in our subway stations prompted robust debate when they were first proposed.  Many felt they were the thin edge of an invasion of our commuting space by relentless video ads especially on the vehicles.

Those who supported the video screens argued that they were a huge improvement over the old “Metron” displays, and touted the wondrous things this new advertising medium would bring us.  As we all know, the video screens were installed in many stations, and then everything stopped cold.

Where are the rest of the signs?  If this was such an important, profitable project, why haven’t all of the Metron units been replaced, indeed, why hasn’t there been a proposal to increase the number of screens?

Many stations, notably Davisville at TTC Head Office, still have Metron units, some of which are operating with ancient news items or commercials, not to mention clocks that are on time give or take a few hours.  These were supposed to be long gone, but they linger on.

One important function claimed for the screens was the ability to broadcast system status information.  How can you do this when many stations don’t even have them, and those that do have only one on each platform, and none in other areas?

Could it be that the advertising market is only lucrative for busy, high-activity locations such as Bloor-Yonge Station?

Is this an example of the shortcoming of expecting the private sector to provide an important piece of infrastructure that should be everywhere, but which is only where they have a hope of making money?
