Over the winter D821 has had the B end engine removed to repair a suspected leaky liner. The work also included removing both the exhauster and compressor and these were overhauled, cleaned and painted and now are waiting to be refitted into the loco along with the engine. As soon as this work is completed D821 will resume its duties with the Severn Valley railway.

D821 is one of the two preserved Warship locomotives from the original 38 built by BR at Swindon Works. Sadly none of the 33 built by the North British Locomotive Company in Glasgow were saved for preservation.

'Greyhound' is based on the Severn Valley Railway and is used throughout the running season and at diesel events.
