TOPS Loco Pool Codes

TOPS Locomotive, Depot, and Pool codes – top page


The following is a list of TOPS Locomotive Pool Codes which can be used in conjunction with the locomotive stock changes in the “Railway Observer” which is published monthly by the Railway Correspondence and Travel Society.

There are a number of codes which are still “live” on the system, but they have no allocation and are unlikely to be used.

Finally, two ghost pools (DXXB and DXXC) are on the system; these, together with a number of ghost locomotive numbers, are only used for staff TOPS training purposes.
