The tram circuit is continuous with the pit head and consists of a loop of corrugated iron and brick sheds. On the N (downhill) side the pit head has a rubble stone plinth. Above this is brickwork incorporating 3 square-headed windows. The brickwork continues into the tram circuit, although here the elevation is mainly of corrugated iron.
