Like i said, I have no idea how the trains got from Point A - south of the TTC - to Point B - in the station, where they are now.
Clearly they moved north into the station at some point to evac the guests off Purple.
WHEW! I've been reading this thread for hours (with a multi-hours break to go see a movie). I didn't want to chime in until I'd read everything on here.
While I admit this is pure speculation, I have a theory on how the trains got back into the TTC station. Imagine you're backing up in your car or other vehicle. You hear a BANG and a thud. What is your first instinct? To drive forward again, away from whatever it is you hit.
So my (totally speculative) theory on the sequence of events *if* Pink backed into Purple is:
-Pink, for whatever reason, is backing into the station on MAPO override.
-Purple was either arriving at the station (would have required MAPO override) or was stopped just outside the station. I've been on trains that come to a full stop just before entering a station before, well past the typical hold-point out over the parking lot. Or perhaps the reverse movement of Pink gave Purple a red MAPO light, and Purple came to a stop where it was.
-Pink runs through the station and hits Purple.
-The driver of Pink is momentarily startled and freezes, then pulls forward, away from the collision. This pause would coincide with the witness statements of a 10-15 second pause before going the other direction.
-Because the two trains are now mangled togther, Pink unknowingly pulls Purple along with it into the station, where the videoed rescue occurred.
Again, this is a purely speculative theory, based on what I've read on here.
There are two possible operational changes that I could conceivably see them implementing in the future:
One is the installation of some sort of camera on each end so that the driver can see what is at the *other* end when driving in reverse.
Alternatively, any train movement that requires movement in one direction followed by going in the other direction, whether it be beam switching or otherwise, will be a two-person job. One driver at each end of the train, each driving the train "forward" for their particular part of the process so that at no time is any monorail driver driving blind going backwards. Each driver would have the full view out their windshield. I don't know the specifics of how the monorail software is set up, but I'm sure this wouldn't be TOO difficult to add.
