LMS Jubilee Class 5596 Bahamas is a preserved British steam locomotive.
45596 Bahamas was built in 1934 by the North British Locomotive Company in Glasgow for the London Midland & Scottish Railway. 45596 was designed by Sir William Stanier and entered service in 1935. 45596 is the only 'double chimney' Jubilee locomotive after being fitted with it in 1961 as part of a trial. This trial was the final attempt by British Railways to improve the performance of its steam fleet.
In 1967, Bahamas was purchased from British Railways for preservation by the Bahamas Locomotive Society. After this, it was sent to the Hunslet Engine Company in Leeds after which it appeared in March 1978 carrying LMS crimson lake livery as No. 5596. Its latest overhaul (2013-2019) at Tyseley Locomotive Works was supported by the National Lottery Heritage Fund and Bahamas ran again in 2019 on the main line for the first time for 25 years. As No. 45596, it now runs in BR green livery.
Bahamas was the very last engine to be experimented on in BR's attempt to improve the performance of its steam fleet in the 1960s and its recent overhaul to main line running condition was achieved with support from the National Lottery Heritage Fund. The loco only runs a limited number of tours each year and when not in action this 1934-built engine is usually based at the BLS Headquarters at Ingrow on the Keighley & Worth Valley Railway in Yorkshire.
