The points/signals from the sidings can only be set for one route (which
is into the westbound platform).

I can appreciate that, having suffered many "terminating at Wood
Green" trains when heading for Bounds Green in the past, but how
feasible is it to reverse the set-up? I would guess that that would
rest on how long the central section of the line is likely to be
US....

I gather some tests have been planned/undertaken today although I have
no idea of the scope of them.

Without any signalling alterations, it would involve scotching and
clipping the point blades in position as required. So it would be a
normal signalled move into the sidings, someone to secure the left hand
point blade into position and then authorise the driver to make the move
into the eastbound platform. In these sidings they are two separate
blades so as to create a catch points effect when neither of them are
set.

I'm not too sure about the passenger benefits of extending to WGN only -
pity we can't get to Finsbury Park, at least then we would be linked
back into the network.
