Last Wednesday, I presented a memoir at the the Société de Transports de Montréal’s (STM) consultations on the “Vendôme Access Project”. The STM plans to build a second entrance and pedestrian corridor at Vendôme Station, to link together the Metro station, the commuter rail station, the new MUHC hospital, and the residential area to the North of Vendôme. The project will also add elevators, which will finally make the station accessible to people with reduced mobility.

Originally, I did not plan to attend these consultations, and hoped that the STM would come up with a reasonably efficient design. However, after seeing the video mockup of the new station, I found the STM’s proposal inefficient and decided to participate after all.

The main issue: long-winded transfers that force commuters to take stairs up and down and up again, without any escalators.

The STM always presents the project with an image that shows a modern, airy station building, presumably one that passengers would enjoy using:

While very pretty, this image does not represent the actual user experience of most travellers, who do not exit at Vendôme, but instead want to transfer between the AMT and STM trains.

Those transferring from buses will not be using this new entrance. In fact, this new édicule will essentially be used by residents East of the station and people with mobility issues who need the elevators.

The majority of passengers, those transferring between the Metro and the commuter trains, will perceive the station like this:

A 104m transfer, 3 times the geographical distance between the 2 platforms, stairs totalling 94 steps that make users climb 3 times the actual height between the overground and underground platforms. No escalators, and those who need elevators must take 3 separate elevators along the way.

The walking distance is more than the existing concourse at Vendôme, which has a transfer length of 88m to 105m (depending on which platform you are coming from) and ~60 steps.

This is surprising given that the physical distance between the platforms is much shorter at the location where the new transfer will be built. One should expect the new concourse to have a shorter transfer!

Effectively, the new concourse squanders the opportunity for a shorter, more efficient transfer, made possible by the better positioning along the platforms, by instead providing a transfer-walk which is worse than the existing one!

And this matters, because people really hate wasting time in transfers. Transit agencies consider the psychological penalty of transferring to be more than two times the actual time it takes for the transfer. The problems are exacerbated by the many long flights of stairs, which require more time and effort.

In the end, when users have to choose between taking the car or the train, these extra minutes during the most inconvenient time of the commute may tip the scale and result in many people choosing driving over transit.

Why Vendôme Matters

Vendôme is an important transfer point between the Orange line and 3 commuter rail lines. These lines form the “CP division” of the commuter rail network. While these 3 lines see about 33,700 passengers per day, the infrastructure is very much underutilized. This is largely due to the limited number of trains (low frequency), more expensive fares compared to the STM, and lack of stations in NDG (between Montreal-Ouest and Vendôme).

The CP line passes through one of the densest areas of Montreal that is not served by rapid transit. Several bus lines running parallel to the corridor have more ridership than the commuter rail lines, so the demand is clearly there.

At the same time, Vendôme sits in the corridor that is the main access point downtown from the West of Montreal, and there have been multiple proposals to connect various areas using this line. If utilized better, this line could easily triple its ridership.

Still, the rail line has one major issue: the quality of the connection downtown. The terminal station is Lucien l’Allier (built when access to Gare Windsor was cut off by the construction of the Bell Centre). It is located downtown, but the walking distance to many work places is rather long.

Work places in Eastern downtown can not be reasonably reached by walking — commuters will have to use the metro to reach them.

Note that Lucien l’Allier also has a connection to the metro. But this transfer is rather long, because of the distance between the metro and AMT station locations and the depth of the metro station.

Vendôme station is therefore the most important transfer to connect the AMT CP division to downtown.

How Could We Fix The Proposed Design?

Thanks to a question during the information session by Matthew MacLaughlin, who runs metrodemontreal.com, the STM was asked to provide plans for the new station. Starting with those as a template, it’s possible to analyze the “constraints” that were often mentioned during the question session, when people asked about the inefficient design.

During my presentation at the consultation, I made the following suggestions for improvements:

Proposal 1.1: Connect the STM and AMT concourse

If we look at the proposed connection, we see that inside the green area highlighted in the below image, the paid Metro area (blue) and the AMT tunnel (grey) almost touch. But since these areas are not connected, passengers are forced on a detour up and down stairs, just to get on the other side of a wall.

The area highlighted in green looks like like this at the metro platform level:

Again, you see the paid Metro area on the left (highlighted blue) and the AMT area on the right (highlighted grey), separated only by a wall.

At the information session, the STM claimed that the AMT and STM areas don’t have exactly the same floor height — but the plans they provided do not show that. In fact it appears that people transferring from the Metro will have to walk up 31 steps on the right, then down 31 steps on the left, meaning the floor heights should be the same. Any difference should be minimal, and the floor height of the AMT tunnel could easily be adjusted to match the Metro platform.

If we realize that the main problem is the absence of doors in the wall between the AMT and the STM, we could fix it like this:

Here, I simply added doors between the AMT and the STM area. The heavy turning doors are required because the STM needs a closed system for ventilation purposes. Note also that I removed one set of stairs on the left, and one elevator, because they have now become redundant — people coming from the left can use the stairs and the elevator on the right. Note also the added turnstiles, which passengers have to pass through to get to the metro platform.

Proposal 1.2: A single Concourse for STM and AMT

One of the quirks of the proposed design is that the station is divided into two completely separated areas: one with a paid fare area for the STM (with its own ventilation) and one for the AMT, which uses proof-of-payment and different ventilation. This is very strange, given the constrained space.

Basically, the planners of the Vendôme Access Project beautifully created a large amount of space by taking it from the adjacent bus loop and building. They then filled the space with all sorts of infrastructure, dividing it and making the space cramped and hard to use. It also means the AMT area does not benefit from the large window facade.

But it would be possible to have a shared concourse, by placing the whole station under STM ventilation and having turnstiles closer to the platform. This is done like this for example at station Bonaventure.

A single, shared concourse can allow an even better connection between STM and AMT:

In the diagram above, we see that by opening up the space, we can now have two connections between the metro platform and the AMT tunnel, reducing walking distance along the platform to reach the tunnel.

Proposal 2: Escalators!

At information session, the STM was asked why no escalators were planned. They said there is not enough vertical space. This makes sense when we look at one of the cross-sections they provided:

As you can see, the “machine room” of the escalator would conflict with the existing metro tunnel.

But this problem exists only at this one spot; the various other stairs don’t have that problem!

And even for this one critical set of stairs, it would be possible to add escalators if we lowered the floor above the metro tunnel and move the stairs Westward, which will provide more clearance under that “crash-wall”.

This would allow us to add one upward escalator:

Proposal 3: Maximize Tunnel Level, minimize Mezzanine Level

The design so far has reduced the length of the transfer between the Southern metro platform and the AMT concourse from more than 100m to about 40m. To make an impact in the other direction, i.e. the transfer between the Northern (Westbound) metro platform and the AMT trains, we should try to remove the total number of stairs.

Optimizing this transfer essentially requires raising the AMT tunnel up, and lowering the mezzanine above the metro tunnel down, like so:

As the the two levels move towards each other,

• the total number of stairs required for transfers from the Northern metro platform to the AMT goes down,
• long flights of stairs will be turned into several shorter flights of stairs, which require less effort.

In an ideal world, the Metro tunnel should have been built lower or the AMT tracks raised at some point, so we could have a single mezzanine strategically placed between the Metro and the commuter rail platforms. Building this now would involve such a large impact on the existing infrastructure that it would be too optimistic to propose.

However, without making major changes to the existing construction, we could still maximize the floor level of the AMT concourse by using a very low height for the tunnel (2.20m), and a very low profile rail bridge.

This would result in three split levels: the Metro platform level, the AMT tunnel, and the mezzanine above. They could each be about 2.20m apart:

The area between the Eastbound Metro platform and the AMT tunnel, could look like this:

The above design can easily deal with any separation between the STM and AMT level, up to about 2.5m — as long as a single, shared concourse is used between AMT and STM. Note the efficient use of the available space, the insertion of elevators in the constrained space between the “crash wall” (dotted line) and the existing metro tunnel, and the arrangement that allows adding an escalator for every set of stairs.

So using a single, shared concourse between AMT and STM, rather than two separated turf areas, together with some optimizations, we can significantly improve the transfer experience for tens of thousands of passengers.

Conclusion: Participate in the Consultations and Demand Improvements!

I believe my presentation has at least piqued the interest of the Commission (the president thanked me for the “well-researched and thoroughly thought-out presentation” and another wondered whether I was an architect).

After my presentation, I also spoke with attendees who seemed interested in the ideas I put forward.

This consultation has convinced me of the importance for people to voice their opinions.

For this project, many people asked questions about the inefficient design and the lack of escalators at the initial information sessions. But at the session where the public may make presentations, nobody besides me talked about these issues — so although the independent commission was aware of the problems, if nobody had come and complained about them, they couldn’t mention those in their report. It was my impression that the Commissioners were glad to have someone there who talked about station design.

Projects like these are often “designed by committee”, and the public isn’t directly involved. It’s only during the consultations, even if they are non-binding like this one, that we get a chance to “pull up a chair” and participate, and ask for improvements for users.

This time, one person showed up and entered concerns into the record, so there is a slight chance that improvements may happen. This chance increases with every voice that is added to the chorus. Participation is important, there may be nobody doing it for you.
