Nunnery Square works car

The Nunnery Square works car (nicknamed Adolf amongst Supertram staff) was a vehicle operated by Sheffield Supertram during the late 1990s and early 2000s. Not much is known about it's history.
The vehicle passed into Supertram's hands after being put up for sale by Berliner Verkehrsbetriebe, the operator of Berlin's tram system in Germany. The tram was a modified single-car electric unit built for the Woltersdorf line in the 1950s and subsequently heavily modified as a works car.
The vehicle never left the confines of Nunnery Square depot and rarely saw use, even for it's intended purpose as a shunter or yard pilot. Eventually the works car was abandoned completely and stored for several years on a back siding in the depot; at some point in the mid-2000s, it was sold to the Crich Tramway Museum in Derbyshire where it was stripped for spare parts and scrapped.
