This Vanguard diesel-hydraulic was built by Thomas Hill, at their Kilnhurst, Rotherham, works, sometime around 1966. It was built using the frames and running gear from a Sentinel vertical boiler steam locomotive. It was bought for the Shelby Group's warehousing and storage division and is believed to have worked at an oil storage depot, in Essex. It was transferred to Watery Lane for overhaul and possible sale, but could be found in use at Strong's yard during the mid to late 1970s. It continued in use well into the 1990s, right up to the cessation of rail traffic in 2000.
It was popular with the staff at Strong's as it was very easy to drive and also quite powerful, with the turbocharged version of the Rolls Royce C6 diesel being fitted.
