[edit] Answers

  • aerial photo shows two tracks, which might not be two mainline tracks of a double track line.
  • aerial photo shows no overhead wires, so train probably diesel powered, which is consistant with reported fire (from diesel fuel?)
  • train reported to have concertinaed (aka telescoped). Telescoping less likely with strong couplings.
  • reports of "light" signals would increase likelyhood of track circuits, a device particular good at reducing likely of collisions.
  • burst into flames imples diesel trains with flammable diesel fuel.
