Nostalgia & History > SP passenger car and loco number duplication?Date: 03/18/07 22:23 SP passenger car and loco number duplication? Author: brassmag When SP had passenger cars during the 50's and 60's for example, just about all of them seemed to be a four-digit number. How did they handle on paper or in the "system" any duplication with a four-digit locomotive?

which conflicted with some engine numbers. Later on, the cabooses had a 90 added to the front of the 4 digit ones. Date: 03/19/07 12:54 Re: SP passenger car and loco number duplication? Author: RD10747 Different classes of equipment had their own numbering
system, ie: Santa Fe express psgr reefers were in the 4000 series as was some 2-8-2 steam locos... Date: 03/19/07 13:17 Re: SP passenger car and loco number duplication? Author: Waybiller Having duplicate numbers would have been possible up until the computer era, as I'm not aware of any railroads having car type be part of the 'key' in equipment identification, but I'm totally ignorant of the really early car control systems.
It would have had to have ended by the TRAIN and UMLER era of the early 1960s, at minimum. Date: 03/19/07 21:00 Re: SP passenger car and loco number duplication? Author: brassmag For example, when someone was told to check or repair an axle on SP2942 how would an employee know to track down a coach or locomotive?

Author: vcrail If the 2942 was a passenger car it would be in the coach yard and be looked at by a coach yard employee, if locomotive 2942 was coupled to it the coach yard employee would not even look at it as it is a locomotive which only gets worked on at the engine house. It would be just the opposite at the engine house if a coach was there.
