the openings allowed better access through the body sides and Lion had central access doors for servicing. The driver's doors were also openings in the truss, which could extend to the full length of the bodyshell and cabs. Engine cooling was performed entirely in the roof section above the cant rail, explaining the lack of large cooling grilles in the body sides. The cooling group was provided by Serck and used two radiators in a removable pack in the roof over the Nº1 end and the Spanner Swirlyflow steam heating boiler. Air was drawn in from the sides, through the panels, and exhausted upwards in the centre by two electric fans. The main roof section, above the engine, was unusual in that it was a translucent fibreglass moulding, which provided light into the engine room, despite the body's small windows. This lightweight moulding could be raised upwards by pneumatic cylinders when stationary, to act as an air vent before needing access to the engine. The roof could then be slid lengthways, allowing fairly major engine servicing such as piston replacement, without needing a large overhead crane to remove a metal roof. The oil-wetted engine air filters were also mounted in the roof section, leaving more space in the body. The external styling, particularly the cab design and its fibreglass roof panels, resembled the Class 35 Hymeks, as they shared the same designer. The outer cladding skin was a load-bearing steel sheet. As such skins otherwise tended to show uneven ripples, Lion had this stiffened by five lengthwise fluted ribs. The livery stood out from other locomotives, although also showed dirt, as it was painted white overall with the side ribs picked out in gold. Testing BR tested it initially on Western Region services out of London Paddington based at Wolverhampton Stafford Road Shed. Later it moved to Finsbury Park on the Eastern Region for services London King's Cross. However, BR decided to purchase its new Type 4 fleet from Brush Traction (the Class 47) and so D0260 was withdrawn in February 1964. Disposal Full details of Lion's final withdrawal have never been fully made public, and even the BRC&W workforce were not informed of its fate. But at some time after withdrawal, Lion was moved to AEI's works at Attercliffe where AEI became responsible for stripping the locomotive, primarily to recover their electrical components. During this process Sulzer recovered their
