Class 66

This changing market has encouraged both existing and new operators to base operations on a reliable locomotive fleet which has been met by the Class 66 design. The expansion of the locomotive's operating area has been recorded within the book through a regional analysis noting both the freight services operated within the region and the companies providing them. This also notes changes of operators, both by exchange of locomotives and exchange of hauler as contracts are re-negotiated at regular intervals. Fred Kerr's book seeks to show, as of October 2019, the range of services that have been operated by class members, including the occasional passenger services despite the locomotives not being fitted with any heat generating equipment.
