They were named after British mountains, and consequently nicknamed Peaks. OverviewIn part inspired by LMS prototypes 10000 and 10001, and by Southern Railway 10201-10203, the Class 44 diesels were some of the first big diesels commissioned for the British Rail modernisation project and were the precursors to the Class 45 and Class 46 locomotives of similar design. PowertrainA Sulzer 12LDA28-A diesel engine drove a Crompton Parkinson GC426-A1 main generator which supplied power to six Crompton Parkinson C171-B1 traction motors.[1] Train heatingWhen initially put into service, the locomotives were fitted with multi-unit working and steam heating boilers for passenger service. They worked regularly over the West Coast Main Line for a couple of years, and also between London St Pancras and Manchester Exchange. Freight serviceOnce the Class 45 units were available, the steam heating boilers were removed and the Class 44 locomotives were assigned to freight duties. They mostly operated in the East Midlands, all being based at Toton until 1980. {{clear left}}Fleet details
