Tops Codes
Tops Codes
TOPS has been used by BR and its successors since the late
1960's to keep control on locomotives, multiple units, coaches and wagons
together with train locations and formations. TOPS is slowly being phased out by
other programs such as MARS and Genius but to this day TOPS can still provide
information for the enthusiast. These pages are designed to give a brief history
of TOPS and to hopefully decode all those mysterious numbers and letters used on
TOPS reports. The pages still need a lot of work on them and if you can provide
me with any information then please contact me at matt@railnet.free-online.co.uk
or I can be faxed on 0870 063 7859.
