Clearly there isn't much faith in planners here when they change their mind a million times (see: Eglinton subway and Sheppard subway)

^ Maybe they plan on short-turning there eventually.

It's for efficiency at short turning the trains to avoid delays and decrease of service level.
I suspect they will do the same for Steeles Station on the Yonge line
When the metro went to laval, they built a third plateform

A train which is short-turning at Steeles West will pull into the middle platform which will keep it out of the way of trains continuing through the station. The driver will need to walk to the other end of the train, go through a checklist, and then leave southbound. If all this occurred on the other tracks trains could end up getting backed up because, as can be seen at Kipling, trains arrive before the reversing train departs. The extra tail track handles larger bottlenecks or holds a spare to make it easier to get rid of the bottlenecks and spacing issues quicker. It is all about operational flexibility. Anyone who has waited on a train into the last line stations can attest to the fact things get bogged down where trains turn around.

With no crew at all and fully automated trains it would still be tricky to do it at a station like Finch simply due to the time it takes a train to get through the switches.
To comfortably maintain 90 second headways means you need to be able to achieve ~60 to second headway bursts to close operational gaps.
The 7th car (slightly longer train) won't help matters at double tracked stations with no pocket.
Since we don't want to tighten the cross-over distance (bumpier ride) we get this configuration.

Immediately, actually. The idea is that they're going to short-turn every second train at Finch and Steeles West in order to marginally increase capacity on the line.

I thought the plans included a pocket track just north of Downsview for short-turned trains?

They are building a third track south of Downsview instead.

Yeah, I saw that in the plans. It seems unrelated; I'm assuming that the purpose of that track is to ensure that any "backup" of trains getting into Wilson yard after the peak periods don't block the through trains. I don't think it's there to permit trains to turn back.
Anyone know for sure?
I've always thought that Wilson is a more logical turn back location than Downsview or Steeles.

. But of course knowing the TTC they'll get lazy and won't change the bulbs after they burn out.But a turnaround track will be more useful.

It looks like the current short-turning of trains at St. Clair West will now occur at Glencairn, starting sometime in 2010. I don't know the exact target date.
This will be followed by in 2015, by short-turning at Wilson.
They are waiting for the arrival of additional trains (3 by 2010, and 9 by 2015) for the needed service capacity, before they can do so.

Only two tracks according to the Conceptual Design.

And if they only run 1 in 4 trains up to VCC how long would you have to wait for a train at that station, and how long would you have to wait for a train anywhere on the line that actually goes to that station.

at peak period; 4 * ~90 sec = ~ 6 mins max
