The colour scheme on those trains is like Canada on the outside and Sweden inside Green instead of yellow poles would have put it more in line with Ottawa's corporate colours

Yellow poles is standard on OC Transpo buses:

Good Day...

re photo : 'Progress of construction at Parliament Station cavern'

So much for looking down on trains from the concourse level down into the tunnel transitions. Oh well. <sigh> Did not really expect it, but it would have been nice.

That picture looks to me as into the tunnel from the station, not the concourse. I may be wrong though.

Good Day....

nope... it's from the tunnel, looking through the transition, into the station.
The side-by-side boxes are the LRT train guidepaths, with the Y centre column support in the middle holding up the concourse level floor, above which you see 12 and-a-half courses of concrete block mortared into place at the end of the concourse level. (Why that big pipe in the left side guidepath is where it is is a good question though; I would have thought it would be better positioned on the concrete faces at the end of the twinbox towards the camera. But then, what do I know?! <snort> !)

EnJoy!

Yep, all downtown stations are going to be narrow, ugly and claustrophobic.



I still don't understand why they designed them with side platforms which goes against original recommendations of island platforms. Here's excerpt from 2009 Planning study:

The rail corridor and configuration of the platforms in the downtown tunnel is based on the most efficient design to traverse the core. A centre platform, with an east and west bound LRT track on either side can be effectively and economically constructed as the tunnel boring machine (TBM) works its way through the limestone bedrock under the downtown area. The centre platform avoids duplication of stairways, escalators and elevators, thereby saving costs. This configuration also minimizes entrance and wayfinding requirements associated with other platform types. Supporting infrastructure and equipment needs are minimized and the platform creates a safer environment since there is a higher likelihood of multiple passengers at any given time and it is easier to secure the area in case of an emergency.

If I had to guess, I would say that we got side platforms because the trains are running in the center of a single tunnel. If there were a single, central, platform at each station, then the trains would need to split apart and come back together for each station; which would mean a lot more rock removal at each end of the stations.

On the other hand, if each train ran in its own, separately bored, tunnel, then the tubes could be as wide apart, or as close together, without requiring any more spoil being generated. In this case, central platforms at stations require nothing special. Of course, if you want a track cross-over between those to tunnels, then you would need to remove material between them; just as you would be removing material between the tunnels for the stations.

It was less expensive for RTG to use Road-headers to mine the single tunnel over a longer period of time than to use TBMs to bore separate tubes and then use Road-headers to clear out the stations and required cross-overs. The added cost of doubling the escalators and elevators obviously did not offset the saving from mining.

If the trains are assembled in Ottawa, why are the seats and floor (mats?) wrapped in plastic?

I think the colour scheme of yellow bars and blue seats might have something to do with visibility and safety (in case of emergency, grab the bright yellow bar, fast!) It might also be better for the visually impaired, but that's more of a guess. Other transit systems have it.

For one, they ended up using a mining technique as opposed to the TBM.

Here's an article about accessibility complaints around the Eglinton Crosstown centre platforms.

Centre vs. Side platforms. Biggest pro with side platforms is the increased speed and acceleration through the tunnel.

And Rideau Station with a more open design compared to Lyon and Parliament, so not all downtown stations are claustrophobic.

It's weird because wheelchair advocates generally want center platforms, but blind people want side. You can't please everyone. But yes we have side platforms, as does Montreal because we have a single tunnel rather than twin tubes. With twin tubes then center platform is the cheapest option. I do kind of wish they did the open thing with Parliament and lyon too but at least Rideau has it

In this YouTube video I just watched this advocate for the disabled talks about how side platforms are better for the blind because they can easily tap their canes against the wall to navigate the platforms and put their backs up against the wall until the train arrives. His organization is concerned that the Eglinton Crosstown will have centre platforms.

I assume that might be because they have more room to navigate with their wheelchairs, but with the design of the Confederation Line platforms (downtown at least), the elevator opens up on the side (away from the track) on a wider part of the platform, so it gives them the room they require. You can clearly see it on the Rideau Station rendering.

Final assembly was done in Ottawa, but I believe the components were manufactured elsewhere. Most likely the seats were made elsewhere and shipped (wrapped in plastic) to Ottawa. They likely kept the plastic on during assembly to keep them clean and won't take it off until they see passengers to ensure they stay that way.

That image was rendered before the art was selected. The platform will have "11 laser-cut painted steel panels, nine feet tall by 20 feet long, depicting the small, low growing plants that line the paths and trails across Canada. Each panel design describes plants specific to one of the many ecological zones of the country, starting toward the west end of the platform at Parliament Station with the Pacific Maritime and progressing through the Mountain, Arctic, Boreal and Prairie to the Atlantic."

This is the city where people, including the Mayor, bought into BS about a terrist bringing a bomb onto the subway train and "blowing up" Parliament Hill from a vertical separation of tens of metres of rock, and a horizontal separation of hundreds of metres.

People: not smart.

Was there ever talk of running it under parliament hill? Can't imagine that being a good route, terrorists aside.
