... actual station as it was from 1870s until it was rationalised in the early twentieth century, so there's not much room for adjustment -- in a constricted site, the single entrance track has to be able to access each of six platforms, and to exit any of the platforms, lines have to access the single exit track. Anything you could offer to help things move on would be most appreciated. One response could be: 'find another prototype', but after 40+ years of pipe dreaming...

I'm not convinced all the crossings can be checked, but if the prototype could do it, then it should be doable in the model, especially if you are using S4-X with exact-scale flangeways. I've had a quick stab at a skeleton of the bottom part, but it's only a guess: 2_261710_180000000.png Please can you attach your .box ...
