Thanks to my being banned from Saturday shopping trips (no real hardship to me) due to alleged bad behaviour on a previous trip, I've been able to address the signalling situation. A guy on ebay was selling sets of homemade signals, 2 and 3 aspect, I emailed him & asked if he could make four aspect, which he did, at a very reasonable price (£4 each including resistors & a really easy to follow wiring * switching diagram. I kitbashed a couple of gantries from Ratio kits (these are utterly freelance, but if anyone would like to tell me how to improve them I'd be grateful.
So now I have four aspect switchable signals on all four lines through the station, & a 2-aspect starter on the bay platform. I had to hack chunks out of the bridge though to thread the wires through, all repaired now & looking pretty good. Many thanks to the ebay guy, if anyone wants his details I'll be happy to pass them on. & thanks to all of you for your suggestions and advice.
(you wouldn't want to see the wiring behind the control panels though - luckily it's all hidden.)

Oh, and it looks like that large building has earned a reprieve:
