MAINLINE STEAM LOCOMOTIVES 2017
This page lists steam locomotives which have current or recently expired main line running certificates, or are expected to receive certificates within the next year or so. Note that locomotives require an annual main-line operating certificate (indicated in col headed "12mo cert") which includes a boiler inspection. This may be renewed annually for up to a maximum of 10 years, subject to at least one major intermediate inspection and re-tube of the boiler, normally after about 5-7 years. often locomotives are withdrawn from service before the end of the 10 year period. In the table below the initial boiler certification is shown. In some cases certification is for operation over London Underground Ltd track only (indicated by (2) in 12 mo cert column).
In the latest Network Rail Group Standard (GO/RT3440) published June 2007, steam locos hauling passenger trains are normally limited to a maximum speed of 60mph, except for a few locos with driving wheels of 6ft 2in diameter or larger which are approved for 75 mph running. Locos with driving wheels below 5ft 8in diameter are normally limited to 50mph, and those below 5ft in diameter are normally limited to 35mph. (A few locos such as 9466, 48151 and 76079 have derogations allowing them to run faster than these new limits). Lower speed limits normally apply when running light engine or with a single coach. Tender locos travelling in reverse are normally limited to 35mph, but may be towed in reverse at speeds up to 60mph.
Speedometers and BR AWS are now compulsory for all main line locos. TPWS was required from Jan 2004. OTMR data recorders are now compulsory from March 2007. A dispensation (dsp) was allowed for one or two locos which were withdrawn from mainline use by the end of 2007.
Steam locos can normally only run with vacuum braked coaching stock. However some locomotives have now been fitted with steam powered air pumps and air brake controls for use with air braked coaching stock (indicated in col "air brk"). In many cases the loco itself retains vacuum or steam brakes as originally designed, but in one or two cases the loco has also been converted to air braking. Some other locos (not indicated) are fitted with through air brake pipes and controls (sometimes temporarily) for operation in conjunction with diesel or electric locos fitted with air compressors. The designation "i/h" denotes work in-hand.
Locos are identified in this table by their British Railways running number. Some locos are currently running in prenationalisation liveries with corresponding number which is shown in square brackets under the Loco details column. All main line steam locos are allocated a five figure number "98cxx" for use in TOPS, where "c" is the former BR power classification 0-8, and "xx" is usually but not always the last two digits of the loco running number. A full list of steam loco TOPS numbers may be found here (pdf file).
