I bought a Weaver Central Vermont and a NYC Pacemaker freight car from Public Delivery Track. I ordered it with the diecast trucks and couplers.
I also obtained a MTH Santa Fe box car that needed trucks and couplers installed.
Since two of the cars were in 1970s paint schemes or the maintenance data was from the 70s, I added ACI plates to each side. The “Kar-Trak” system was used by US railroads from 1967 to 1977...

The New York Central Pacemaker car Is another future project. The paint scheme depicts the car that was in captive service on the NYCS. They normally were not interchanged with other carriers. This explains the lack of dimensional data on the right side of the car sides.
Later, the Pacemaker service declined and the special boxcars were placed in general service. At that point they had dimensional data added as the cars were repainted. Some cars survived in the grey/red scheme in general service with the data added.
I plan on adding the dimensional data to this car, so it can run, historically correct, with other railroad cars in my freight trains…
