i was thinking the same. in short you cant because due to the huge curve of the station the gaps at the middle doors of carriages would be huge.

I remember reading something like this many years back when people become stuck between the platform and under ground train in the usa, and 9 times out of ten when the fire service e.t.c turned up they say we are looking at a dead man even thou the person is still alive because the bottom half of the body has twisted and once the train was moved then you can guess the rest.
ps.I am aware that this is a little different just thought i would offer some useless information.
I thought it was Meatloaf.
How on Earth did he fall into that gap? I can't see how it's possible.
Wrong.
One of the articles linked on here specifically states that the box belongs to a man on the platform who tried to use it to stop it crushing him.
I've seen a lot worse pics where a guys head is crushed between the train and the platform.
Can't post pics or links on here for obvious reasons.
