The Golden Valley Light railway

A 2ft (610mm) Narrow Gauge Railway in Derbyshire

Baguley Drewery 3703

This locomotive was purchased from the army in working order (although adapting the charger to run from a 13A plug rather than a heavy 3 phase supply required some ingenuity) and arrived on site on 16th December 1994. It had been rebuilt by Hunslet Barclay in 1986, and worked at RAF Chilmark until that depot closed.

The two axles are separately powered, each having a 25 HP flameproof 100V DC motor driving through a worm gear reduction. Two completely separate sets of control and power electronics and reversing contactors are fitted. Control ranges from the exceedingly delicate to the totally brutal depending upon the whim of the driver.

Locomotive Specifications
Built - 1974 (rebuilt 1986)
Power - 50HP
Volts - 96
Weight - 5 tons

The battery, consisting of 50 lead acid cells, is estimated to have had a capacity of approximately 750 Ampere hours when new, and comprises about half of the loco's 8 tons total weight. If the electronics can be made reliable and the battery sufficiently rejuvenated, the loco could be equipped for air braking and (theoretically) work 6 or 7 return passenger trains between charges. During construction of the railway, it was used to haul trains of up to 20 tons from Newlands Inn.
