The engineer may not be aware of the vertical movement of track beneath his train. I do not know about prototype maintenance procedures. Also, look again at the 8 minute 1944 O.S.S. "Derailment" video, which Rich Gajnak mentioned in June, to see how hard it is to wreck a train: <http://www.realmilitaryflix.com/public/212.cfm?sd=61> Long story short: they had to remove 60 inches from one rail, 30 inches from the other rail and offset the centers of the two gaps by 30 inches in order to derail the cars following a 2-8-0; the engine itself did not derail. The key to success was to cause enough vertical movement to pull the spikes out of the ties and allow the rails to fall out of alignment. When we first discussed this video, Lee Johnson pointed out that it's much easier to derail a train on curved track, instead of the straight section the O.S.S. used. -- Bill Roberts ------------------------------------ Yahoo!
