Built in 2000, the Garratt answered a need for more power on the railway, which featured tight curves and gradients of up to 1 in 10. A locomotive type boiler pressed to 120psi provides the steam, the power bogies are connected via an ingenious coaxial pivoting steam and exhaust connection.
Steel locomotive boiler with expanded copper tubes, working pressure 120psi, feed by axle pump and injector. Stainless steel superheaters. Twin safety valves. Two power bogies, each featuring cast iron cylinders with slide valves actuated by Hackworth valve gear, pole reverser working via balanced pulley block system. Mechanical lubricator. All wheels running in roller bearing axle boxes. Steam brakes with screwdown hand brake.
The engine is in running order with a new boiler certificate (and the diesel was coupled up as a test load rather than a banker, in case you were wondering).
