W.G. Bagnall 4wDH Shunters

Most of the diesel shunters made by W.G. Bagnall had mechanical transmission (such as 3147-3150 for example), however the last few shunters built by the company before their takeover by English Electric had hydraulic transmission. The last two locomotives were built for Leys Malleable Casting and were fitted with a British Twin Disc single stage torque converter which was linked to the wheels via a Wiseman reversing and reduction gearbox [1].
