I learned a lot about Pennsy and Belpaire boilers with one question (not what I
wanted to see...they rarely emigrated to other lines). Now I wonder if there are any cabooses still being used in revenue service anywhere in the Hew Hess Hay, maybe on a branch as just a rider car, or as a transfer caboose in a yard, or...??? (not counting tourist roads, where I have ridden in them and seen them) I know that manpower costs led to their demise, but wonder if any other factors such as federal safety law changes had an impact, as I'm guessing it had with the disappearance of full ladders on freight cars.
Any idea when the last one ran, or is some road, Class 1 or industrial
captive still running them?
