It seems odd that on reaching the HB platform he didn't think to turn
back on the direction he had headed from the train in the Edgware
platfom. How many times had this driver driven a train through
Camden.

I conclude that the driver thought he had been told to reverse.

Is that possible? Is there a crossover he could have been heading for? Our
survey (of Tubeprune's Northern line signalling diagrams):

Says yes - there's one just north of Mornington Crescent; does that fit
with the description of the incident?

If it was a shunting move to get him onto the correct route, this
wouldn't be necessary.

But if the driver thought he was turning that train and taking it south
again, he might have been heading for the crossover. That isn't what he
was told to do, but there could have been a communications breakdown.

Shouldn't either have these have required a wrong line order?
