Background and design

In 2007 the Hunslet Engine Company announced that it was developing a new shunter type, with a family of diesel hydraulic designs (B, C or B'B' axle arrangement) up to 100 tonnes posited for future development, in 2008 manufacture of the first model - a 60tonne, 3 axle machine began.[3][4] The first locomotive of type DH60C was unveiled at Chasewater Railway in July 2010.[5][6]

The locomotive applied modern design principles to a shunter designed for the UK market;[n 1] the locomotive has swing arm/coil spring suspension, with vertical hydraulic damping, and pneumatic brakes. The transmission is via a hydrodynamic converter and cardan drive shafts to right angled gearbox drives on each axle.[1][2]

Test trials of the locomotive were carried out at Daventry International Railfreight Terminal.[7]

A four-wheeled variant is also being developed, and Hunslet intends to certify it for use across the UK's national rail network.[8]

Notes
  1. The design is built to the standard UK vehicle gauge - as defined by drawing 'UK L-A1-1806'.[1]
