That was very interesting, but unfortunately also convinced me that the designers are getting ahead of themselves with the automation. In particular, apparently the only way of moving a train with an open door involves making it invisible to all the signalling equipment. That is crazy. There should be a way of telling the train to ignore the open door, but still exist as far as the signalling system is concerned. Of course this shouldn’t be done carelessly and should require authorization from central control.
When the problem with the train is just a stuck door, the only aspect of moving the train that matters is passenger interaction. Once the train has either been evacuated or the door area blocked with a tarp (or people just moved away from that part of the car — we’re not completely stupid, in general), the train should drive exactly like any other train. He talks about needing to use written movement authority for a train with a stuck door. That should only be needed for a train with broken CBTC equipment. What next, the train won’t move if the air conditioning is broken?
