I just shot the 2015 Canadian SASS Champs where the theme was "Hell On Wheels". Every stage was a railroad scenario, including one that was a engine, tender and car.
Took a lot of effort to create and set up. If it can't stay set up, it becomes a PITA to store.
Best props elsewhere were large rock formations constructed of Styrofoam covered with tinted cement. Two men could pick one up easily.
