This act could have injured or killed other people - fire spreads rapidly on a train because of the air rushing in to feed it at high speed.
My sympathies lie firmly with the driver. Fire on a train is one of those nightmare scenarios you really prey will never happen to you.
As soon as he saw the flames he would have known that he a duty to save his passengers. An Emergency Evacuation is one of those things that you you do under enormous pressure at great speed....and then all the "experts" examine afterwards at their leisure with a fine tooth comb.
And when he approached the toilet he would have smelt that someone had died in there. Absolutely horrendous, because at that stage he would have seen it as his responsibility to have saved her, not knowing it was a suicide.
This really is a traumatic experience. There is a very real chance that he won't be able to drive again.
It's a sad example of the crazy way this country is going, if you know what I mean.
