Should have said that, as a creekside building it will sit at Dock level. This will be behind the viaduct section,with some space to the right of it, as in the prototype for land side vehicles to load/ unload. So part of what I have drawn of this building will be hidden.
In my world, ground then rises to the other buildings that will sit at roughly track level beyond the carriage sidings. I'm thinking a sleeper boundary fence to the right of the viaduct wall will partly obscure them. Will hopefully get to mock this up in the not too distant future.
