Exactly ! Since the modules are set up at shows and can be observed from both sides, a backdrop makes no sense. Interestingly, I didn't expect the comments to be about the backdrop or lack there of on a module that features interlocking rods that are seldom if ever modeled in N scale.
One of the things I DON'T get to model on Spur 4 is an interlocker. I've long wanted to give it a try. Bill's build is stunning. My AC&Y/W&LE Spencer module crossing is an electrical plant. Drat. Hiles tower, the ACY/Big 4 crossing at New London, modeled as "the donut" by
@btrain, is a full mechanical interlocker. We discussed how he might do that some time ago but I think he's fully committed to the Water Level Route FreeMoN build these days.
