Bachmann Branchline 32-376 Class 37/4 37429 "Eisteddfod Genedlaethol" in Regional Railways Livery

-áThe first-áElectric Type 3 diesel locomotives were-áordered by British Rail in 1959, a-átotal of 309 of these diesel electric locomotives were built and-ápowered by a 12 cylinder-áEnglish Electric 12CSVT power unit. The construction took place at the works of Vulcan Foundry and Hawthorn Leslie Darlington. Many of the components used on the class were shared with the class 40's and 55'; one of the main parts used was the bogie which was fitted to 50s and the 55s. The first 37 eneted service in December 1960 at Stratford shed (30A) and was put straight into-ápassenger duty on Liverpool Street to Norwich and Clacton services, plus mixed traffic duties throughout the rail network. As part of refurbishment programme a number of changes took place, including lower gearing on some locos to increase the traction effort. Other locos were fitted with extra ballast and some had new more powerful motors fitted thus creating a number of sub-classes.
