Diesel Hydraulic Locomotive
(Also known as the WAGR B Class Diesel Hydraulic Locomotive)

Narrow-gauge, hood-type 0-6-0 shunting locomotive rated at 396/353kW (531/473HP)

WAGR B class diesel hydraulic locomotive

"The unit is powered by a Cummins engine driving through a three-stage converter and clutch to a final drive reversing gearbox and jack shaft. Drive to the wheels from the flycrank is by forged coupling rods. Suspension is by laminated leaf springs on top of each axle box. Compensation is provided between the leading and intermediate axles.

"The engine is mouned rigidly on the main frame and is fitted with twin oil-bath cleaners. Two radiator panels are mounted vertically. one on each side of the hood at the opposite end top the driver's cab.

"The radiator fan drive is hydrostatic. The locomotive is fitted with both air and vacuum braking systems.

"The lightweight superstructure features a high cab and low hood profile to provide the driver with the best possible view in both directions. The cab is fitted with dual controls so that the locomotive can be driven in either direction.

"The whole superstructure is bolted to the all-welded steel underframe. All hood components can be lifted off to give complete access to the equipment during overhaul. Side doors are provided in the hood for normal day-to-day inspection."

Ten of these locomotives entered service with the WAGR between March 1962 and November 1965. All are now out of service and four have been preserved. You can find more information about the WAGR B Class diesel hydraulic locomotive here.
