“How did they get the fire truck into this boxcar?"... the answer? An end-door boxcar. Pennsylvania Railroad had them made for the very purpose of delivering American LaFrance (thanks Steve!)

this 1955 American LaFrance 85’ aerial ladder truck cost $36,750. It wasn't retired until 1983

notice that the top photo shows the fire truck in a Pennsylvania box car!  The LaFrance was shipped out of Elmira, New York 

Thanks Steve!
