All it shows is that LUL have little in the way of fall back
procedures in place when things go pear shaped. A broken door or dodgy
signal should not end up with 5 trains worth of people stuck in a
tunnel for an hour. Broken signal? Fine , drive through it on caution
and let everyone detrain.

Co-ordinating all the trains that have to move through that signal takes
time. This has knock-on effects on the rest of the line.

Whats the problem? Broken door? Reverse
train back into platform , empty pax and take it away again. Sorted.

Not safe if you don't know precisely *how* the door is broken. I
certainly wouldn't want to be on a moving train with a broken door,
because I don't know whether the door might just randomly open, or fall
off, or whatever. And if it falls off and gets tangled up in the
undercarriage, or damages some trackside equipment, then you've just
made the delays a whole lot worse.
