Pullman-Standard came up with a system for identifying freight cars in the 1930's or 1940's.
PS-1 Box Cars
PS-2 Covered Hoppers
PS-3 Open-Top Hoppers
PS-4 Flat Cars
PS-5 Gondola
A majority of the cars built by Pullman-Standard in the final decade before being taken over by Trinity were the Box Cars, Covered Hoppers, and Flat Cars.
When were the last Pullman-Standard Open-Top Hoppers and Gondola Built?
The few photos and models that I have seen of these cars show that the production on the PS-3 Open-Top Hoppers and PS-5 Gondolas might have been in the early 1960's.
Does anyone know the history behind the Pullman-Standard production levels?
Thrall Car and Greenville Steel Car Company were big competition to Pullman-Standard, so that might have been why the PS-3 and PS-5 were not built in the 1970's and 1980's.

This is an upcoming publication by Signature Press. I might have to purchase it and other Signature Press titles sometime. It will cost $65 so it better be thorough for that price.
