Bombardier back in 2009 and started rolling them out onto one of the busiest subway lines in North America in 2011. Why did it take 3 years to get these trains rolling? Because the original door supplier went bankrupt, so Bombardier said gently caress it and did it themselves. One new feature on this train is that if someone gets caught in the doors as they're closing, the door servos detect it and recycle the doors. This was supposed to reduce problems with the doors because previous train models used pneumatics and someone forcing the doors would burn out the motors. Subway drivers and supervisors at the TTC discovered quickly that if the doors cycle more than 3 times in a row, the onboard computer throws a hissy fit and the entire thing must be taken out of service and rebooted. During rush hour, trains and platforms are packed like clown cars, so you can imagine the delay and frustration. The TTC got mad at Bombardier and they had to software update the trains. After that happened, the doors still had software glitches and twice in one week this happened:  Anyone leaning against those doors would have been crushed or fried on the power rail. This has since been fixed (again) and hasn't happened anymore. However these trains consistently create jams and uneven headways on the line because the doors are slow to open from stopping and the train is slow to go from doors closing. It's more likely than not if you're waiting a while for a train, it'll be this one followed closely behind by several old trains. The cab door on the side of the train is purely decorative and art for the foreseeable future. These trains are made of stainless steel and are somehow starting to rust before they reach their terrible 2s. Other notable features of each $13 million piece of poo poo are:
Door glitches are not restricted to new Bombardier trains. Old Bombardier trains were doing it too!

), for persistent problems mainly with the doors. The last straw was when one of them refused to close its doors in the central S-Bahn* tunnel

ninmeister posted:I've heard about these awesome problems on the TTC trains. It's sorta mind blowing that there isn't relay logic involved to drop propulsion on the train in the event of a door opening while the train is moving (I'm assuming the train is moving when this door problem happened (happens?)) instead of just software. I get relays are sorta being phased out in carborne equipment for PLC based everything but drat, safety sensitive stuff should still be safe. They do. In all these cases the trains were stopped. I did see a video of a really old TTC train (made by Hawker Siddeley, who was bought out by...) cruising down the tunnel with one set of its doors open. Someone must've done goofed for that to happen. I'm guessing they were isolated somehow. When doors break from too many morons forcing them open (can't wait for the train right behind it!!!), the doors often don't close enough for the computer to register them as closed. So the crews disable the doors (so they don't open) and isolate them (so the train can move off). When this happens the crews put large red tarps blocking the doors or take that car out of service.
