Grey represents roads. Light brown buildings. Blue is for the backdrop, and the orange rectangle is an intrusion into the room.
The right hand side of the layout represent North, while the left side will be South, this means that viewing the layout we will be looking West. The plan remains to run trains in from the right hand side, around the hidden staging loop and into the front arrival/departure yard track. There is a run-a-round and I've added a caboose track, which is the short spur to the right hand side of the layout, near the front.
Cars can be cut from the inbound train and switched to all the spurs. The run-a-round allow the kick back spur to be handled too. in addition there is a team track for anything else to be unloaded on the right hand side of the layout.
The upper track layout has been simplified to capture the basics of what I want. The impression of elevated track that will see CNS&M cars running along it, and as and when maybe I will be able to get some CTA elevated cars too.
The two levels are not connected to each other, as I don't have the room to model the ramp. Trains can be run through the hidden return loop, or can be reversed once entering the staging area to represent a Northern bound train.
It is not totally ideal, but it is the best I can do in the space that I have. Unless someone can suggest any major improvements?
