These diesel-hydraulic locomotives were purchased from the Ministry of Defence Railway Lydd Ranges (Kent) in 2007, where they were used to transport personnel and equipment on the extensive railway system within the ranges.
Originally four locomotives were purchased, one has since been sold to Statfold barn.
The three remaining locomotives have been repainted and are seen in regular use on the OKLR, thanks to their electric start capability.
