And can you reverse in both directions at Victoria, Warren Street
and Seven Sisters? Again, the tracks would allow it, but what about
the signalling? Or is it all done manually?

Victoria is principally a south to north reversal - either via the
sidings to the south or the crossover. In theory you could run a train
north out of the n/b and reverse back over the crossover into the s/b
but I've never heard of that being done.

Victoria was built with a scissors crossover at the North end, wasn;t
it? Why on earth did they remove it?

I think you're right. No idea why they were removed.

It. The trailing crossover was left in the crossover cavern.

Because Victoria has got a second scissors crossover south of the
station and two central reversing sidings. When the service is buggered
from Victoria to Brixton it can be used to reverse the southbound
service. The original scissors crossover (just like the one that used
to be at Highbury) is thus redundant.

I appreciate it's redundant, but then it turns out not to be so on
occasion when other equipment fails. Some redundancy makes it easier to
cope with failures.

My surprise is that the facility was removed having been installed. It
would have cost very little just to leave it there.

True, but in theory the simultaneous failure of the signalling in
Victoria South Sidings and the trailing crossover north of the station
should not happen. The fact that it did does not mean that having a
scissors crossover in position would have changed anything.

Not necessarily - if that were the case the scissors crossover west of
Liverpool Street (Central) would not have been simplified either, and
yet it was - and Liverpool Street has the same arrangement as Victoria.
