There was an interesting succession of large 2-6-4 tanks that developed from the Fowler 4P tank, first modelled by Hornby in 1980. The tanks were developed by the London Midland & Scottish Railway to pull heavy commuter trains in the North London suburbs, a job they were particularly suitable for. When Stanier succeeded Fowler as CME for the LMS in 1932, he was soon to develop his own version of a 4P 2-6-4 tank which had its distinctive tapered boiler - an influence of Stanier's former days at Swindon. This is the version that has now been modelled by Hornby. Stanier was succeeded briefly by Fairburn who introduced a lighter version of Stanier's tank and the final version was one developed by Riddles for British Railways and famously modelled in the Hornby Dublo range in 1954. The Fairburn and Riddles tanks have both been modelled by Bachmann.
