GWR Route: Banbury to Wolverhampton
Whitnash Cutting: gwrwh3910
Great Western Railway 2-6-0 26xx (Aberdare) class locomotive
heading south through Whitnash Cutting (away from Leamington Spa) with a train
comprising a large number of Greaves Cement Vans. The locomotive is carrying a
class K Lamp Headcode (Ordinary Goods Train, stopping at intermediate
stations). The photograph date is not given, but believed to be early
1920s. Because of the large number of Greaves Cement Vans in the train
are almost certainly destined for the Harbury Cement Works (see 'Greaves Sidings'). For a close up of
these vans see 'gwrwc3910a'.
The Aberdare class locomotives were designed as freight
locomotives principally for the South Wales Coal traffic and although
relatively few in number, they proved to be a successful and long lived class.
Many worked mineral trains between South Wales and the Northern Divisions of
the Great Western with a strong allocation at Newport and Oxley sheds. The
first Aberdare class locomotive (No 33, later changed to No 2600) entered
service in August 1900 featuring a typical Great Western short cone domeless
standard boiler with a Belpaire firebox and this standard No2 boiler was also
fitted to the following forty locomotives (Nos. 2621 - 2660). The boilers in
these initial locomotives operated at a pressure of 180lbs, but the next twenty
locomotives (Nos. 2661 2680) were built with a slightly larger diameter
(standard No4) long coned boiler operating at 200lbs. This raised the
locomotives tractive effort at 85% from 23,222lb to 25,800lbs (power
group D). With this larger boiler the maximum axle weight was 17tons,
10cwt which restricted the locomotives to main routes and a few branch lines
(Route colour - Blue). For details of the Great Western Railways
locomotive classification system see 'Engine Map'. The initial locomotives were
subsequently rebuilt to carry the standard No4 boiler, and another twenty
locomotives (Nos 2601 2620) were also constructed. Further improvements
such as; superheated boilers were introduced in December 1908, and top feed
apparatus added in March 1911. At first the top feed was a separate mounting,
but later this was combined with the tall safety valve cover as seen in this
photograph. By the late 1920s short safety valve covers had been
introduced. The first three withdrawals (No 2621, 2627 and 2641) occurred in
September 1934 and the class then slowly reduced until only thirty-one were
left by the end of 1938. With war clouds on the horizon the next five
locomotives to be withdrawn were not scrapped, but kept as a strategic reserve
so that they could be reinstated if war was declared. Withdrawals resumed in
1944, but twelve survived to serve British Railways and the last (No 2620) was
withdrawn in August 1949.
