    there is no 'bend' of mentionable merit anywhere between the original parking spot at 1685 feet elevation and the town 'flat' (the trainyard itself would be flat) of 1312 feet elevation. The distance between original parking and the derailment conflagration is just over 13 kilometers. The engines and first few cars traveled another kilometer beyond the town, apparently to where the track leveled out and began climbing again (plus curve, exerting drag via friction).

    The entire unit was no doubt moving at a clip when it hit the 'Y' at the trainyard and the derailment happened. Once derailed, the bulk of the train would be subject to chaotic forces, energy transferred in unpredictable directions, that's the utter disaster here. The front part of the train (per this info) didn't derail, coasted along the track another kilometer before settling to rest.

    All I'm saying is that the 'extra' kilometer isn't surprising to me, given this particular scenario. None of this explains why the brakes failed - ALL of 'em - setting the train in gravity's motion when it should have stayed where it was parked. That's the mystery, and the crime (if there is one). It's not like you can lean against a braked train to light a cigarette and send it suddenly careening more than 13 kilometers downstream or something...

      Really appreciate your clear explanation what makes sense to you in simple physics terms.

      Those pictures of the derailed tankers all piled up are incredible; but I always think derailed trains are incredible.
