Just how hard is it to cope with a light stuck on red?

Firstly you need to determine why the signal is red - stuck train,
broken track, or failure of the signal system.

Secondly, if the signal protects something like points, you need to get
them secured before allowing trains to run over them.

Thirdly, the service is intensive enough that the delays in "tripping
by" can completely screw up timings, leaving trains and train crews in
the wrong place.

Fourthly, if the problem is trackside then someone needs to go and fix
it before the service will get back to normal. This requires stopping
trains while they're working on the particular bits of equipment.
