Pardon my (continuing) ignorance, but what does the designation "PS" mean in regards to rolling stock and engines? I don't mean "protosounds", but PS1, PS2,
PS4, etc. It seems to be associated most with scale sized equipment, near as I can tell...

sula,

The PS refers to the Pullman Standard standardized line of rolling stock manufactured starting in the 1940's by the Pullman Standard corporation.

Not sure but I will try, I think that "PS" stands for some type of hopper car used in grain or cement travel by rail. Or some model railroad companies have come up with this one. PCS-1 & 2 are digital remote control made by MTH.
