^^The TTC is considering adding a 7th car to the TR trains to increase capacity. The car is expected to be 50ft, rather than 75ft. Considering the modular nature of the trains, I do not see any reason why the 7th car cannot be added later.
 
Well not really precisely, just to make sure the all the doors access the platform. And even with manual driving there could be painted lines and something that goes beep and stuff.
 
Weird...I thought I remembered reading somewhere that they ordered fewer trains than the number that are currently in service on the line.

The original order was for 39 trains (234 cars), fewer trains than the 47 currently on the line. The added 31 more trains (186 more cars) to the order earlier this year to replace all the old H6 equipment (21 trains, 126 cars) and for the new trains for the Spadina extension.

Once all 70 new trains arrive by the end of 2013, they will all be on the Yonge-University-Spadina line, and the 372 T-1 cars purchsed in the late 1990s will be on the Bloor-Danforth and Spadina lines
 
70 seems like a lotta trains, even with the extension :O
Nonetheless, thanks :p

Well, bear in mind that they are also retiring the H-series entirely, which includes the H5s on the YUS line, the H6s on the Bloor-Danforth line and - last but not least - the H4s, marking the last we will see of the large vinyl padded benches.
 
ATC is operational

Boys n girls I wouldnt hold my breath for this yet.......they are having a lot of problems with the speed control as of now I dont even think the trains on Sheppard are using it
 
Agram, I think you might be right, I only saw it being used once, since then, which was about a year ago, I've never seen it operational, and I ride the sheppard line frequently. What does speed control do exactly if I may ask?
 
I think it does exactly what it says, it keeps the train's speed limited to the "speed limit" of each track section. It's the last outstanding recommendation from the Russell Hill accident.

Speed control does refer to the actual speed of the train, but it also takes into account the position/ speed of all the trains on a system. ie in order to control the speed of train A, the ATC must know exactly what every other train in the system is doing, and what the other trains are going to do next (like is it going to slow down for a station, pick up speed etc etc..) Think of ATC and Speed control as like one continuos conference call between all trains, all signals, and all computers. Everything must be coordinated exactly for such a system to work. I have included a few links... hope these help answer your question.

AFAIK the speed control TTC is implementing isn't related to ATC. It's much simpler.
