The Cadillac Sedan Limousine was originally owned and operated by a Toronto Medical Doctor. The Cadillac ran as a regular car on the road. The Doctor was a friend of CPR President N.R. “Buck” Crump and donated the car to CP. CP sent the car to Montreal where it was converted to run on rail. The car was then assigned to the President of General manager as a convenient (and comfortable) inspection vehicle operated as a train for safety reasons. It was driven by Division Superintendents who were qualified operators who could also inform the senior manager about the condition of their division.
The car weighs seven tons, is an eight cylinder and is identified on the track as M-260. The conversion added a turntable underneath the car so that it can be reversed on the track, as well the driving wheel became part of the air brakes. Furthermore air brakes, an air horn, and a bell were added. The car has only 32 000 miles on.
