| With the abandonment of Bulleid's "Leader" project the
issue of the introduction of intermediate range tank engines in the Southern
Region had still not been resolved. Whilst memories of the use of heavy tank
engines with leading pony trucks lingered on after the Sevenoaks disaster it was
clear that the lastest LMS 2-6-4T locomotives seemed to have a good pedigree
starting with the Fowler, through Stanier to the current design by Charles
Fairburn. It was decided then that the Fairburn class 4 engines should be built
at Brighton for use on the Southern.
Of the total number of 277 Fairburn engines 41 of them were built at Brighton in 1950 and 1951. They were classified by the LMS as 4P and by British Railways as 4MT and formed the basis for the British Railways Standard class 4 2-6-4T engines. The most obvious difference between the Fairburns and the Standards was the curved profile of the Standards' tanks, cab and bunker where they followed Bulleid's least controvercial innovaton of designing his locomotives so that the profile followed the curved profile of his coaching stock. Many of them were stationed at Stewarts Lane in Battersea, Dover and Ashford(Kent) for use on the South Eastern Section. One of the routes which became a favorite stamping ground was the Maidstone to Ashford line on which one notorious derailment of one of Maunsell's River class had taken place at Bearsted. Two of the Brighton-built locomotives, N°42073 and N°42085, survive in preservation on the Lakeside & Haverthwaite Railway. |
