In the 1970s the introduction of the merry-go-round coal trains required a far more powerful loco, leading to the 3300 hp Class 56 being built. For general freight services, the Class 60 was developed. Both these types suffered from reliability problems in their early years. Several large stone companies in Somerset became frustrated with the constant loco problems that BR were having and decided to order their own locos, choosing General Motors in the USA to supply them. This resulted in the Class 59, which started service in 1986 and proved to be so effective that other Railfreight operators followed suit and ordered what became Class 66. Eventually, more than 400 entered service.This book of mostly unpublished colour photographs, taken by George Woods between 1966 until 2019, show the locos hauling a variety of trains all over the BR system.
