5542 - '4575' class tank locomotive, owned by the Locomotive 5542 Limited. The locomotive was rescued from Barry Scrapyard in 1975 and moved to the West Somerset Railway for restoration. The PFP (Planet's Favourite Prairie) steamed again in October 2002, for the first time over 40 years.

These locomotives were the final development by C B Collett of the 44xx class, introduced in 1904 by G J churchward. In all, some 185 were built. No 5542 was built in July 1928 and features the larger wheels, sloping tank tops and outside steam pipes characteristic of the later batches.

These reliable and popular engines could be found throughout the Great Western, outside of London, handling passenger and freight traffic; some were fitted for working 'auto' trains on push-pull services (although 5542 was not so fitted until preservation). 5542 was first allocated to Gloucester. Its final allocation was Westbury from where it was withdrawn in 1961. You can find out more about 5542 on the 5542 website.
