Whilst travelling home from Camden, Southbound on the Edgware Platform I
noticed two amber flashing lights, just inside the tunnel mouth ahead of
where the train stops on the track.

Any idea why they are there?

I thought the derailment happened at the cross over, which is the other end
of the platform.

John Alexander,

The whole of the train has to pass completely over any affected section
before it can resume normal speed and this would probably an indicator to
resume normal line speed.

John Alexander,



In this case, this is the "T" for the end of the temporary 15mph speed
restriction. The "15" being before the crossover.
