The 45651 is a steam locomotive built in 1937 for the London, Midland and Scottish Railway. It was used for hauling express passenger and heavy freight trains across the United Kingdom before being withdrawn from service in the 1960s. After being restored to mainline standards, it is now a popular attraction for steam train enthusiasts and regularly used on steam train charters throughout the UK. Its black livery and impressive performance make it a favorite among railway enthusiasts and an important part of British railway heritage.
