British Railways Standard Class 4MT 2-6-4 Tank Locomotive No 80064 was built at Brighton, outshopped  in June 1953 and was initially allocated to the London Midland Region before transferring to Southern Region ownership in December 1959. It was transferred to Exmouth Junction following the electrification of the Kent Coast railway. In September 1963 Exmouth and the area was transferred to Western Region control and so it then transferred to Western Region ownership.

80064 was withdrawn from service in September 1965 and sold to Woodham Brothers at Barry for scrap. It arrived in the scrapyard in October 1965 and remained there until February 1973.

Following the purchase by the 80064 Locomotive Fund, the locomotive was moved to Buckfastleigh on the Dart Valley Railway (now the South Devon Railway) in 1973 where the long task of restoring was started.  80064 steamed again in 1981.

In 1984 the owners moved the locomotive to the Bluebell Railway where it worked for a number of years until its boiler certificate expired around 1989.

Towards the end of 2023 locomotive 80064 was donated by its owning group  to the West Somerset Railway Association and relocated to the West Somerset Railway where plans are being made for its restoration.

 Locomotives of this type have been used on the West Somerset Railway in the past and proved ideal for the challenging gradients and heavy loadings experienced on the WSR: the longest full-size preserved railway in England. It will be ideal to replace the locomotives currently in service, when they are withdrawn on expiry of their boiler certificates, over the next 4 years.
