3850's History

At the commencement of the 20th Century, the Great Western Railway was in need of motive power capable of dispersing trainloads of coal from the South Wales collieries, the existing 0-6-0 and 2-6-0 designs of the day proving inadequate.  By 1903, Churchward had built a prototype 2-8-0 design, number 97 (to be renumbered as 2800 in 1906), the first locomotive in the UK to utilise this wheel arrangement.   Production of the 2800 class of locomotives commenced in 1905 and detail modifications took place during the build, totalling 84 locomotives.  Twenty years after the last of the Churchward designed 2800 locomotives had been built, Collett, Churchward's successor as Chief Mechanical Engineer at the GWR, when he recognised the need for more heavy freight locos, created the 2884 class. This was effectively a 2800 with minor modifications.  Visually, the most obvious change was the use of external steam pipes (which were retro-fitted to many of the 2800 class locos), a tool tunnel on the fireman's side running plate and the addition of cabside windows.

The specification for the 2884 locos was as follows:

Driving wheel diameter        4' 7.5"
Cylinders                              18.5" x 30"
Axle load                              17 tons
Total locomotive weight        76 tons

Water capacity                      3500 gallons
Coal capacity                        6 tons
Firegrate area                       27 sq ft
Tractive effort (85%)             35,380 lb

3850 was amongst the last to be built, entering traffic in June 1942 and surviving in servce until practically the very end of steam on the Western Region of British Railways in August 1965.

3850 went new to Bristol St Phillips Marsh shed, but when British Railways came into being in 1948, it was based at Westbury. Allocations (from 1948) - Westbury, Severn Tunnel Junction, Aberdare, Banbury, Oswestry, Croes Newydd.

As a freight engine 3850 led a rather unglamorous life as it plugged away, day in and day out, on heavy freight workings. However, in December 1952, the 2-8-0 must have surprised many when it steamed into Paddington Station with a parcels train. She managed to top this, when in August 1957 it was “copped” at Exeter with the down Devonian!

The three digit reporting code in the above photo was replaced by a four digit one in 1960.  As the train is heading south, the 7 indicates that it started in Swansea or West Wales, prior to the change in 1958/59 when the leading numeral indicated the destination.

Interestingly, the headlamp code for the above photo would appear to indicate that it is running as a partly fitted freight, which doesn't tie in with the stock behind it.
The occasional foray from freight working aside, 3850 managed to keep out of the limelight until September 1965, when it was seen at Brymbo steelworks with an iron ore train, despite it having been withdrawn a month earlier! By the end of 1965 the loco was in Barry scrapyard and there she stayed until March 1984, when she became the 151st loco to leave.
