This question could go in many forums (Real Trains/Scenery) but I thought it would be fine here too.
Just read a great article in Classic Trains: All Aboard! in which the author stated that Pennsy engines took water on the fly from track pans with a scoop.
I have never heard of this procedure and I am curious if anyone could explain how the pan was imbedded in the track and how the water was stored/replenished. Was there an adjacent tank?
Does anyone model this pan on their layout? It could be a really interesting scene.
thank you
