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.

Acccident Report

 * Accident Report

Observations

 * ATC - mentioned in report
 * "A console that identifies trains and their locations to control tower staff was also not functional." seems to say that track circuits and/or a signal box indicator diagram weren't working.
