I'll bet the building code for earthquakes has been beefed up since the Expo Line was built (i.e. post-Kobe and post-1989 S.F.)

Technically, the Expo line is more stressed because of the combined frequency of the Expo and Millenium Lines.

Great pictures btw!
They actually did beef up part of the Expo Line recently. That is what I observed when I drove along Terminal Ave. Looks like they did some reinforcing where the column meets the T portion...

Yeah, that was for the added weight of the MKII cars - someone on the forum mentioned that that stretch was the original "test track", so it was built to a different spec than the rest of the Expo Line.

It does make me wonder if the Canada Line guideways are even designed to handle more than 2-car trains.

Probably just to the spec of the "expanded" trainset - i.e. consistent with the extended platforms.

oh. wow.....taxpayers are spending $1.4 billion on this project and we're not even building it right.

Whether it is "right" or not is subjective. They would be required to build it to the requirements set out by Canada Line Co. They won't spend more than they need to - and if they did, the taxpayers' share of the costs would increase ....

It's a balancing act. The system "as is" was tough enough to finance. Tack on a bunch of extras and it probably would not have been built at all.

New Canada Line pics at their website.

The guideway between the Operations and Maintenance Centre and Bridgeport Station. Note the extra clearance above the rail line.

Here's a pic of the Vancouver City Centre Station excavation (south end) with the tunnel portal marked in orange:

Scans of the plans and renderings for the Vancouver City Centre Station from the DPB Report.

As mentioned earlier, City staff did not like the concrete fin wall (although it is a common element with the other downtown stations - see pic of Waterfront Station, above - not much left architecturally if the fin is removed.

Note the glass pavillion for the southern emergency exit.

Interesting drawings. Can you post a link to the site? Are there more drawings for other stations?

I went to the open house on 16th on Monday. I wanted to get a concrete answer on how the decison was made for the short 40m stations. Most people don't have a clue, I know more than the ladies that work there. A few other more senior people where there like a construction supervisor, but no definitive answer from them either.

Some interesting facts for the tunnel sections: there will be no emergency exits between stations, but instead the tunnels will have cross connections in the form of sliding doors, kind of like the Massey tunnel.
There also won't be any ventilation or exhaust shafts between stations. Apparently each station will have powerful fans to ventilate the tunnels.

will it be a problem without ventilation?
like.. in such emergency..
where passengers have to evacuate the trains..
and also, will the trains and stations be with air conditioners?

well all that counts is that there will be powerful ventilation for the tunnels, and it's located at the stations.

the trains will be air conditioned, the stations will not.

Sorry, they're scans of a hardcopy of the City's Development Permit Board reports. The same ones posted on the City's website, but on the website they omit the appendices with the drawings.

WRT the station platform length, the Concession Agreement with IntransitBC (available at the Canada Line website) provides for an ultimate build-out capacity of 15,000 ppdph - it was up to the bidder to design the system to meet that specification. The agreement specifically states that the platform length is up to the bidder. It appears that InTransitBC is using wider cars (3.0m wide) but shorter trains and frequent service to meet the capacity spec.

*****

The tunnels will have an emergency catwalk for evacuations
