Fairburn Class 4 2-6-4T

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.

42088 Nº42088 Also calling at Faversham but on a Victoria to Dover service in March 1959. Since the conductor rail is now in place on both lines this photograph seems to have been taken shortly before the withdrawal of steam services

42096 Is this proof that at least some of the Fairburns qualify as truly Southern locomotives? A shot of taken in January 1950 of 42096 under construction in Brighton Works

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 Bulleids 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. Your author rode behind one of them on that route in 1960 and there was certainly no suggestion of a derailment on that occasion. Two of the Brighton-built locomotives, nos. 42073 and 42085, survive in preservation on the Lakeside & Haverthwaite Railway.
