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

It's possible, and there is a crossover at Mornington Crescent -

should have known from line knowledge.

No? I assume you mean the crossover between signals E29 and E31
shown he

What makes it not accessible? A genuine question - i know nothing
about this stuff. If it can't be got to from Camden, where can it?

From a shunt manoeuvre from Mornington Crescent, I should think. From
that diagram, you can see that there are no signals permitting wrong-way
working except at the points controlling the crossover itself.

There is also, as I discovered this afternoon, an unilluminated STOP
sign (white letters on a red disc) on the left-hand tunnel wall at the
south end of the High Barnet northbound platform at Camden Town.

If the driver entered the rear cab by mistake, he must have been
mightily confused. The main passageway linking the two northbound
platforms is straight and level. As you enter the High Barnet platform
from the passageway, the starter repeater on the platform is clearly
visible. Even if he had, for some reason, used the small passageway at
the southern end of the platforms which is full of steps and bends, he
should immediately have recognised that he was at the wrong end of the
train. The High Barnet platform is a short one, and the rear set of
passenger doors do not open there. He would have had to squeeze past
those en route to the rear cab.
