The locomotive was built in 1934 as LMS 5593 by North British Locomotive Co. at Queens Park, Glasgow.
The North British Locomotive Company (NBL, NB Loco or North British) was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company (Atlas Works), Neilson, Reid and Company (Hyde Park Works) and Dübs and Company (Queens Park Works), creating the largest locomotive manufacturing company in Europe and the British Empire.
In 1936 it was named Kolhapur after Kolhapur, a princely state in western India.
Initially built with a low degree superheat domeless boiler, 5593 received a domed boiler in April 1937.
5593 hauled the train carrying Winston Churchill from Liverpool on his return from talks with President Roosevelt in 1942.
After nationalisation in January 1948 it was renumbered 45593 by British Railways in December of that year.

At Leeds Holbeck it was kept there in good condition to work railtours over the Settle-Carlisle Railway. The locomotive was also given a yellow cabside warning stripe to indicate that it was barred from the electrified West Coast Main Line south of Crewe where it was out-of-gauge. Kolhapur was withdrawn in October 1967.
45593 was bought in good condition January 1968 by the then Standard Gauge Steam Trust (now 7029 Clun Castle Ltd) and moved to Tyseley Railway Museum. It was restored during the 1980s to LMS maroon livery and it returned to main line running at the head of HRH The Duke of Gloucester’s Royal Train from Tyseley to Birmingham Moor Street on 5th June 1985.
In 1994 it temporarily assumed the identity and special livery of scrapped sister and class pioneer 5552 Silver Jubilee for the silver jubilee of the preserved Great Central Railway.
45593 which was repainted into BR green in 1995 was taken out of service in 1997.
The engine is currently in need of a full overhaul at Tyseley Locomotive Works. The overhaul will commence when 7029 Clun Castle has been returned to traffic.
In June 2020 Vintage Trains announced that the locomotive will be overhauled to main line standard with the aim of having it operational in time for the Commonwealth Games in Birmingham in 2022.
