Guillermo, I'm not quite sure what you're asking. I assume these are Pacific Electric rather than Electric Pacific. If you're looking for the actual numbers of the real cars and engine, you won't find any since the Pacific Electric never owned a box cab or any of those 34' Overton passenger cars. They are what's commonly known here as a fantasy scheme, where models are painted and lettered for railroads that never actually owned any of the prototypes.
