CAPPilot posted:While they all have been advertised as RF-16s, I always thought the Lionel versions were closer in configuration to the DR-4-4-15 with the Sharknose body (PRR RF-15 or BF-4 before 1-1-50). Notice the fuel filler location is higher and just behind the front trucks, and the forward sand filler in front of the door.
Anyway, since my PRR layout is set in late 40s I call Lionel’s version a RF-15.
Not only that, but the fuel tank is of the earlier pre 1-1-50 BF-4 configuration as well.
