Modern batteries and RC, you actually could have a working model of those wheeled switchers. Cab interior detail required - they had a huge ship’s wheel for steering.
Everyone who is oon Facebook should check - there are similar groups for many areas and also specific railroads.
I had no idea that such a switcher ever existed. I did see a similar size battery powered vehicle used in NYC for decades to transport paper for printing newpaper at the Boyertown Auto Museum. I cannot find a picture of that one.
Faller makes that car system that allows vehicles to follow a set course along roads. Bet you could rig that switcher to work on that system. Would be. Conversation piece
