There is not.
For the rest of the messages I’m going to refer you to Paul’s message from above, if they play nice to people and reopen the door every time there’s someone else running to the train, no GO trains would depart anywhere on time.
To a point. I've seen completely empty platforms where they've closed the door with a single person on the platform madly running. And then you look at your clock, and see they are 15-seconds early. And one station out from Union, so about to have an 8-minute lay-over.
At other points, they are trying to close the doors with a crowd of people still trying to enter. I can tell you, if half my kids are still on the platform, or already in the train, I am going to hold those doors. (the failure here is to run enough trains).
The trick I've seen a couple of times recently, is them announcing "please move down the platform to an empty door", and about 3 seconds later the door chimes start, and you hear "the doors are now closing". And you wonder what the person who just got tricked, and is now standing on the platform for 30 to 60 minutes - as no one had time to run to a different door, let alone walk safely.
It's kind of like the subway stations, where the chime starts as soon as the door is open, while there's still 3 or 4 people trying to get off. You are told not to charge the doors and let people off.
Subway trains are frequently more packed, and don't seem to suffer the same frequency of door problems in service. Presumably there are design changes they can make that can make the door closing procedure a bit more robust and failsafe.
Hopefully the next generation of cars have more doors, similar to a subway car.
