A copy of the 2002 edition of the National Routeing Guide. The railway network of Great Britain is operated with the aid of a number of documents, which have been sometimes termed "technical manuals", [1] because they are more detailed than the pocket-timetables which the public encounters every day.
A number of different numbering and classification schemes were used for locomotives and multiple units operated by British Railways (BR), and this page explains the principal systems. This section also covers the post-privatisation period, as the broad numbering and classification arrangements have not altered since the break-up of BR.
It is one of the technical railway manuals which exist as part of the operating of the rail network of Great Britain, many of which are now in the public domain. Customers generally encounter the document in specific circumstances, when they wish to prove (or check) the validity of their ticket on a route which might at first not appear obvious.

[2] The creation of new level crossings on the national network is now illegal (the exceptions being reopening unavoidable crossings on brand new lines or reopening closed ...
A mechanical lever frame inside the signal box at Knockcroghery in Ireland Waterloo station A signalbox, LSWR (Howden, Boys' Book of Locomotives, 1907). Mechanical railway signalling installations rely on lever frames for their operation to interlock the signals, track locks [1] and points to allow the safe operation of trains in the area the signals control.
After nationalisation, British Railways continued with these headcodes and the new diesel and electric locomotives and multiple units were built either with a disc/lamp system (now powered by electricity) or a two to four character roller-blind display system depending on what part of the network they were to work.

At the end of the 1960s, British Railways adopted the Total Operations Processing System (TOPS), a computerised system developed by the Southern Pacific Railroad in the United States. All types of locomotive and multiple unit received a TOPS classification, [ 1 ] but the first attempt at applying TOPS was soon modified.
