>>10183726Is O-72 a requirement? I'm looking at layouts for similarly-sized rooms and they all seem to use O-48 as the minimum radius with a few larger curves here and there. If you're familiar with RBP Trains on youtube I could do something similar to his where there's a main level that sticks to O-48 that has the freight yard and stuff, and an upper level using O-72/O-84 that's mostly disconnected to the bottom part of the layout (I'd try to sneak in a gradient to allow a train to go from top to bottom if you want).
