I have 5 modules in a modular layout that will be in a train show this weekend. Will have the milk car, icing station, barrel ramp, sawmill all set up to run from buttons on the outside. I will spend my weekend reloading those! I usually launch a couple helicopters and missiles when it’s not crowded. On my home layout I have a milk car, horse car and corral, log loader ramp, 145 rocket launcher, intermodal crane, and 397 coal loader. So yes, I use operating accessories!
Of course it doesn't always go smoothly, OSHA is still investigating this one:
