80136 was built at Brighton in May 1956. It was initially based on the Eastern Region working on the London, Tilbury and Southend Line (LT&S) hauling commuter services out of London until that route was electrified in 1962.
It spent time under the management of three different regions whilst in Service with BR. It moved from the Eastern to Western Region in 1962 and in September 1963 it was transferred to the London Midland when Machynlleth (along with Oswestry and Shrewsbury) depot were transferred to the London Midland from the Western Region.

80136 was withdrawn in July 1965 and sold for scrap to Woodham Brothers at Barry. It arrived in the scrapyard in June 1966 and stayed there until April 1979.
It was restored on the Churnet Valley Railway where it steamed again around 1990.
By 2001 it was to be found on the West Somerset Railway where it was withdrawn from service in 2008 when its boiler certificate expired. It subsequently went to Crewe Heritage Centre for overhaul but after languishing there for a number of years moved (the boiler and chasis were moved separately) to the North Yorkshire Moors Railway in early 2016.
It is now planned to base the locomotive on the North Yorkshire Moors Railway where it is being overhauled. It will initially be based there for ten years.
