Just getting started on my first O-scale layout (using Fastrack). The space is slightly confined with 4' X 10' for main layout, plus shelf space for a yard. Trains enter from the yard via a wye, so direction of travel can be either clockwise or counter clockwise. The mainline I plan will be a loop having two "towns" (on-line industrial areas).
My question is whether to have the two towns situated so they can be serviced by the same train, or have them oriented so one train will need to turn on the wye to service both?
I'm thinking out and back to the first town, yard switching, then out and back to the second. Any suggestions?
