Clayton Devonport Locomotives RTU 1 & 2

These 2 locomotives were built for the Royal Navy in 2000 by Clayton Equipment and spend their time at Devonport. One can imagine the cargos they handle (which is no doubt top secret) are often very sensitive! The locomotives, which are known as Dennis (RTU 1) and Henry (RTU 2) [1], have a Clarke hydraulic transmission and a Clayton spur and bevel final drive [2]. One interesting feature of the shunters is that they have 2 sets of buffers at different heights.
