As little movement in O scale as you’d see, I don’t think the work would be worth the rewards,….IMO only of course, others may think differently, ….now if that animation peaks your interest, then by all means,….but I do a lot of custom work, and that thought hasn’t crossed my mind, due to what I said above,…..maybe something more achievable like an ashpan effect, where you stop the locomotive over an ash pit, and hit a button and smoke rolls out from the ashpans simulating the steam & smoke generated by the fella running the wash out hose??…..something like that would have a bigger reward than a power reverser squirting out a couple of millimeters …..
