Train room dimensions

The unfinished storage area is where the trains will be. I am currently along the bottom wall. So far I have St. Albans staging with 9 tracks. It goes up a three turn helix to Belfast, where like the old Wiscasset there is one industry and now we can get to the start of the next town. And a couple of industries. If you go the other way out of Belfast, you go up another turn of the helix and end up in Searsport.
Searsport has an actual arrival and departure track and the yard lead can pull a whole track at once. Also the sidings are much longer.
