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.

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.
