British carriage and wagon numbering and classification
From Wikipedia, the free encyclopedia
A number of different numbering and classification schemes have been used for carriages and wagons on Britain's railways, and this page explains the principal systems. Carriages and wagons (either not self-propelled, or part of a multiple unit which has power units distributed throughout a semi-permanent formation of carriages) have frequently had similar arrangements for classification and numbering, so are considered together. There are also links to other pages that deal in greater depth with the particulars of individual types.

[edit] Note on classification
Carriage and wagon classification has never been quite the same as locomotive and multiple unit classification. For most railways, specific types were identified by their Diagram Number. This could simply be arranged by consecutive number, or there could be some greater organisation of numbers so that similar types were grouped together.
However, carriages and wagons have rarely been referred to in general terms by their Diagram Number. Instead, there have been a variety of other codes and designations, which have referred to generic designs rather than specific types. For instance, there were the BR (adapted from the LNER system) and LMS carriage codes, which indicated interior layout or usage. The GWR identified their non-passenger carriages and wagons through a series of animal designations, including sealife for departmental (non-revenue earning) stock, followed by a letter to illustrate detail differences, e.g. Beetle A.
Therefore the majority of the sections below deal solely with carriage and wagon numbering series, though where a particular classification system was used, this is also described.
[edit] Pre-nationalisation arrangements
Before nationalisation in 1948, each railway company devised its own numbering arrangements.
- The Great Western Railway and London, Midland and Scottish Railway (from 1933) adopted a system which allocated number ranges within one series for different types.
- The Southern Railway followed a similar approach, but used two series; one for passenger carriages and one for non-passenger carriages.
- The London and North Eastern Railway numbered its carriages so that the first digit indicated which area it was allocated to.
- The Great Western Railway Diagram Numbers included a letter to indicate the general layout or usage followed by a serial number issued consecutively.
[edit] British Railways
British Railways inherited the stock of the 'Big Four' companies upon Nationalisation in 1948, and also a substantial number of former 'Private Owner' wagons. It also inherited the stock of the Pullman Car Company, when it was nationalised in the late 1950s.
[edit] Numbering system
The numbers of inherited carriages were left unchanged, but were differentiated by the addition of a prefix letter to show where they had originated from, as follows:
| E: | London & North Eastern Railway |
| M: | London Midland & Scottish Railway |
| S: | Southern Railway |
| W: | Great Western Railway |
New carriages to the designs of the old companies were numbered in their series.
In 1951, the first carriages built to British Railways' designs appeared, known as the 'Mark I'. From this time, a new approach was adopted, which involved the use of a prefix letter to indicate the region to which the carriage was allocated. The inherited carriages then showed the letter indicating the region responsible for heavy maintenance, usually the same as the company of origin, as a suffix. Thus new British Railways carriages had no suffix and so were differentiated from the other four series. When the carriages of the Pullman Car Company were added to the mix, their numbers carried only a suffix (indicating regional allocation), and no prefix, as a means of differentiation. The regional allocation letters used were:
| E: | Eastern Region |
| GE: | Great Eastern lines |
| M: | London Midland Region |
| NE: | North Eastern Region |
| S: | Southern Region |
| SC: | Scottish Region |
| W: | Western Region |
British Railways adopted the following numbering system for carriages to its own design:
| 1 | - | 499 | First class Restaurant & Kitchen carriages |
| 500 | - | 999 | Pullman carriages (after Pullman Car Company nationalised) |
| 1000 | - | 1999 | Third class & Unclassified Restaurant & Kitchen carriages |
| 2000 | - | 2399 | First class Sleeper carriages |
| 2400 | - | 2499 | Composite Sleeper carriages |
| 2500 | - | 2899 | Third class Sleeper carriages |
| 2900 | - | 2999 | Royal saloons (later all Royal Train carriages) |
| 3000 | - | 3499 | First class Open carriages |
| 3500 | - | 3699 | Second class Open carriages |
| 3700 | - | 9199 | Third class Open carriages |
| 9200 | - | 12999 | Third class Brake Open carriages |
| 13000 | - | 13999 | First class Corridor carriages |
| 14000 | - | 14999 | First class Brake Corridor carriages |

| 55000 | - | 55999 | Double-ended Driving Motor Diesel Mechanical Multiple Unit carriages |
| 56000 | - | 58999 | Driving Trailer Diesel Mechanical Multiple Unit carriages |
| 59000 | - | 59999 | Trailer Diesel Mechanical Multiple Unit carriages |
| 60000 | - | 60999 | Diesel Electric Multiple Unit carriages |
| 61000 | - | 67999 | Motor Electric Multiple Unit carriages |
| 68000 | - | 68999 | Parcels Electric Multiple Unit carriages |
| 69000 | - | 69999 | Restaurant and Kitchen Electric Multiple Unit carriages |
| 70000 | - | 74999 | Trailer Electric Multiple Unit carriages |
| 75000 | - | 78999 | Driving Trailer Electric Multiple Unit carriages |
| 79000 | - | 79999 | Diesel Multiple Unit Carriages (pre-Modernisation Plan types) |
| 80000 | - | 80299 | Kitchen carriages |
| 80300 | - | 80499 | Travelling Post Office carriages |
| 80500 | - | 99999 | Hauled non-passenger carrying carriages |
Wagons were allocated numbers from 100000 upwards, and the 9xxxxx series was reserved for deparmental (non-revenue earning) carriages and wagons. Departmental carriages have been numbered in the 963xxx, 975xxx, 977xxx, 998xxx and 999xxx series. Departmental locomotives have been numbered in the 966xxx and 968xxx series, though in recent years those locomotives that remain self-propelled have been allocated locomotive Class 97 rather than use these series.
Initially some non-gangwayed carriages were numbered in the 5xxxx series, but these were soon renumbered to 4xxxx when the Modernisation Plan Diesel Multiple Units started to arrive. Another change came when Third Class was renamed Second Class. There had been very few Second Class carriages before this change (mainly used in Boat Trains since ships still used all three classes), and most were absorbed into the larger mass of former Third Class carriages, although they had many fewer seats.
The same series was used for the 'Mark II' coaches built in the 1960s, but when the 'Mark III' carriage was introduced in the early 1970s new number ranges were carved out of the old series. These new ranges were perpetuated for the 'Mark IV' carriages in the 1980s), and were as follows:
| 10000 | - | 10499 | Restaurant and Kitchen carriages |
| 10500 | - | 10999 | Sleeper carriages |
| 11000 | - | 11899 | First class carriages |
| 11900 | - | 11999 | Composite First & Second class carriages |
| 12000 | - | 12999 | Second class carriages |
| 40000 | - | 40999 | High Speed Train Restaurant & Kitchen carriages |
| 41000 | - | 41999 | High Speed Train First class carriages |
| 42000 | - | 42999 | High Speed Train Second class carriages |
| 43000 | - | 43999 | High Speed Train Driving Motor carriages |
| 44000 | - | 45999 | Second class Brake carriages |
| 48000 | - | 48999 | Advanced Passenger Train Trailer carriages |
| 49000 | - | 49999 | Advanced Passenger Train Motor carriages |
| 82000 | - | 82999 | Driving Van Trailer carriages |
The new diesel multiple unit builds in the 1980s utilised the 52xxx, 55xxx, 57xxx and 58xxx series for the individual carriages, all of which were motored. The 55xxx and 58xxx contained a mix of driving and non-driving motors, but the 52xxx and 57xxx cars were all driving motors. In addition, some series have been used for conversions of carriages, e.g. 63xx has been used for a variety of miscellaneous carriages, including generator vans and observation saloons. Privately-owned carriages registered to run on British Railways were allocated numbers in the 99xxx series (which they shared with bullion and exhibition vans).
Another major change came in 1983 when the use of prefix and suffix letters was abandoned, and any carriage which had the same number as another carriage or a locomotive was renumbered. The programme worked as follows:
| 14000-14999 | to | 17000-17999 | to avoid clashing with Southern Railway carriages |
| 16000-16499/ 15500-15999 |
to | 7000-7999 | to avoid clashing with Southern Railway carriages |
| 25000-26999 | to | 18000-19999 | to avoid clashing with Class 25 and 26 locomotives |
| 40000-40099 | to | 40400-40499 | to avoid clashing with Class 40 locomotives |
| 50000-50999 | to | 53000-53999 | to avoid clashing with Class 50 locomotives |
| 56000-56999 | to | 54000-54999 | to avoid clashing with Class 56 locomotives |
| 81000-81999 | to | 84000-84999 | to avoid clashing with Class 81 locomotives |
| 85500-85599 | to | 94000-94099 | to avoid clashing with Class 85 locomotives |
| 86000-86999 | to | 93000-93999 | to avoid clashing with Class 86 locomotives |
Subsequently, further renumberings have taken place as new locomotives were introduced. Most have involved only a handful of carriages, but a major one saw carriages in the 920xx series renumbered to 929xx when the Class 92 locomotives were introduced.
This series has been perpetuated by the privatised railway, though the series have been adapted for new generation multiple unit stock. For instance, the latest diesel multiple units have reused the 50xxx and 79xxx series for driving motors and the 56xxx series for non-driving motors. In the electric multiple unit series, Class 390 Pendolinos have reused the 68xxx and 69xxx series.
