LMS diesel shunters 7059–7068 were 0-6-0 diesel-electric shunters built by Armstrong Whitworth in 1936. Maker's numbers D54-D63. The diesel engine was an Armstrong-Sulzer 6LTD22 of 350 bhp at 875 rpm (400 bhp at 1,000 rpm on overload). There was a single Crompton Parkinson traction motor with a rating of 231 hp (continuous) or 358 hp (one hour). Final drive was by double reduction gears of 11.1:1 ratio and jackshafts.
