The second Selly Oak model spins one of the baseboards 90 degrees to provide a 3ft deep scene that gives me much more road space at the cost of some railway length.
We've taken more liberties with the prototype - that centre industrial/scruffy space is a lot smaller for a start, and the pair of canal branches are gone. A road runs down in front of the arches, which will be blocked in to provide space of businesses.
If you look at the third photo down on this page, there appears to be a gateway where I have added one. Click on it for the more modern view and that roadways is definitely there. Lock-ups under the arches are pretty much a given too as well as making the modelling easier and more interesting.
Another liberty is the addition of a bus stop with pull-in. There really is a stop at this point, presumably for both station and factory, but it's just a plain bit of road marked with an easy-to-ignore pole. We need parking, there should have been more bus space in real life, so we'll fix this on the model.
All this has changed the angles where road, rail and canal cross each other, but I'll deal with that in due coarse.
The important thing is this plan ticks all the boxes. Now I just need to build it.
