IIRC there is a two track siding at the east end of the station. This is
what your first observation relates to. At the western end I think there
is a crossover - I don't know which way it runs. Someone with a bit more
knowledge than me will be pop up with the right answer very shortly.

There are two sidings east of the station as you say; they are the subject
of an urban myth in that Peter Laurie in his book "Beneath the City Streets"
suggested that a cross-passage at the far end of the sidings was associated
with some kind of connection to the government deep-level system or such
like, though my own opinion is that his theory is a load of rubbish. AFAIK
they were used as an air-raid shelter in WW2, but that's about it.

The western end of the station has a simple trailing crossover.


HTH.
