What we all want to do on our train journeys, is to sit at the window seat, facing forward.
..but on my train journeys in the olden-day trains, long ago; ...single compartments, with bench seats, one facing forwards, and one facing backwards....
...I always thought how much better my survival would be, in the event of a collision, if I sat facing backwards...or better still...lying down, horizontal on the seat, facing backwards, legs and feet clear of the floor, with no-one else in the compartment to collide with me!
The good thing about trains, as opposed to aeroplanes....they are already quite near to the ground at the time of the disaster...

P.S...don't ask me to test my theory!...
