Where are you finding code 55 rail?
The bench work is done for my module, and now I’m ready to lay track.
My LHS has neither rail, nor flex. A number of online vendors have it listed out of stock. Hand Laid Track has it, but in a larger quantity than I wish to pay for right now. Just one bundle will keep me busy for a while.
I do have a bunch of ME rail that can be salvaged from a section of a prior layout, but it is weathered and painted, thus a chore to clean up.
