Unrebuilt SR/BR Class West Country/Battle of Britain No. 34090 at Ashford Works open day 1949. (Thanks to Vic Smith for supplying the location and date)

Plenty of young trainspotters can be seen milling around and climbing up to the locos cab. Again, period clothes of blazers and short trousers abound. The loco was modified in August 1960 and withdrawn in July 1967.

BR/Southern Railway unrebuilt Bulleid Class West Country 4-6-2 Pacific No. 34019 'Bideford' at Eastleigh Works open day on 5th August 1964, a hot summers day. Built at Brighton Works, it entered traffic in December 1945, withdrawn from 70A Nine Elms shed in March 1967 and cut up by Cashmores, Newport in September 1967.

The SR West Country and Battle of Britain classes, collectively known as Light Pacifics or informally as Spam Cans, are air-smoothed 4-6-2 Pacific steam locomotives designed for the Southern Railway by its Chief Mechanical Engineer Oliver Bulleid. Incorporating a number of new developments in British steam locomotive technology, they were amongst the first British designs to use welding in the construction process, and to use steel fireboxes, which meant that components could be more easily constructed under wartime austerity and post-war economy.

They were designed to be lighter in weight than their sister locomotives, the Merchant Navy class, to permit use on a wider variety of routes, including in the south-west of England and the Kent coast. They were a mixed-traffic design, being equally adept at hauling passenger and freight trains, and were used on all types of services, frequently far below their capabilities. A total of 110 locomotives were constructed between 1945 and 1950, named after West Country resorts and Royal Air Force (RAF) and other subjects associated with the Battle of Britain.

Due to problems with some of the new features, such as the Bulleid chain-driven valve gear, sixty locomotives were rebuilt by British Railways during the late 1950s. This produced a design highly similar to the rebuilt Merchant Navy class. The classes operated until July 1967, when the last steam locomotives on the Southern Region were withdrawn. Although most were scrapped, twenty locomotives found new homes on heritage railways in Britain.

Although separately called 'West Country' and 'Battle of Britain' Classes, there were no design differences, the locomotives being identical, apart for their names.

A swarm of trainspotters are climbing all over the loco wearing a variety of clothing; shirts, jackets, long and short trousers, with some carrying the proverbial 'duffle bag'. Although there are some steps up to the locos cab, some spotters are climbing on the tender and one can be seen walking along the top of the loco. What would Health and Safety say about that today!
