"This shot ain't none too bad of the rear end of # 303
showing the yellow Scotchlite lettering on the hind end.
I forget where I read it, but somewhere it was written
that the GB&W's RS-2's came equipped with steam generators. That
little "gas pipe" exhaust confirms it. I wonder if the
GB&W ever had occasion to use the steam generators? I thought the
GB&W had given up passenger haulage before 1950!"
