Would this have been at a diamond crossing?

It would sound like it from the article:

when the Piccadilly line train crossed the track immediately in front of him.

What I want to know is why the train had passed a red signal??

which had stopped after going through a red signal

Either:

a) due to a signalling failure, the signaller authorised the train driver to pass the signal at danger. (This is a regular occurance). Obviously when this takes place you have by definition thrown away the built-in protection of the signalling system. It is conceivable for a signaller to allow a train into a section occupied by another train.

b) The train driver passed the signal at danger without authority - which would make it a SPAD

The article mentions that they were looking at the actions of the signaller and that he had been removed from duty - so I know where I'd put my money. (Though he has my sympathy, poor b*****. )

c) It might have been a bit of both. If the driver had spadded, the signaller may have have authorised him to move the train afterwards whilst there was another train making a (legitimate) conflicting move.

No doubt in time we'll get all the sordid details. I'm just glad the two trains didn't meet !!
