I posted this question on the 3 Rail O scale forum and for some reason it was deleted.
My REA VL Baggage car only has one diaphragm. A response I received on the other forum stated that the baggage car is an NYC prototype and this car only had a diaphragm on one end. Maybe so, but it doesn’t look right to me especially on an REA baggage car. I haven’t examined my baggage car closely yet but hopefully both ends of the baggage car are the same and I can order a second diaphragm from Lionel.
Thanks guys for your responses on the 3 Rail O Scale forum.
