Train Wreck Video

This is interesting - although it looks almost as if it was a sideswipe, rather than a head-on collision, since the loco pretty clearly moved onto the diverging line just before impact. The signals displayed a "stop" indication, but it could well be that the train that occupied the main (which looked as if it was stopped) was too long for the passing track, which the moving train meant to occupy - and got a little too close to the switch.

(h/t, Drudge).
