CP had quite a fleet of the 60 wood baggage cars, and a good proportion of them were rebuilt with a steel under frames and steel reinforcement of the ends of the cars. This model is one of those steel reinforced cars and they lasted well into the late 50’s and maybe the early 60’s in mainline service. Some of them sported big cowl ventilators with weathervanes on their roofs in ‘ventilator service’ for shipping fruit in the summer season on the head end ends of regular passenger trains.
The wood coaches lasted a long time as well in ‘suburban service’, which I think would have been commuter or other short distance local trains. The baggage cars, being steel reinforced, could be operated on any train, but the coaches could not be operated in a consist with steel cars.

And here, I think, is the prototype for the baggage model (my info for 1954 shows 159 cars from this class still in service, many with steel underframes, but majority steel reinforced wood, and all meeting US interchange requirements)
