The Class 59 Co-Co diesel-electric locomotives were built and introduced between 1985 and 1995 by Electro-Motive Diesel for operation in Great Britain.
With Foster Yeoman dissatisfied with the availability and reliability of British Rail's Class 56 diesel freight locomotive, and their satisfaction with their EMD SW1001 shunter, four Class 59/0s were ordered from Electro-Motive Diesel (EMD) which arrived at Southampton on 21 January 1986. A new design to the British loading gauge and specifications, derived from the EMD SD40-2, it used the cab layout of the British Rail Class 58 to aid driver assimilation.
They were the first United States built and the first privately owned diesel locomotives to operate regularly on the British main line, although EMD powered locomotives have been the mainstay in both the Republic of Ireland since 1961 and Northern Ireland since 1980.
Following Foster Yeoman's example, Amey Roadstone Construction ordered four Class 59/1 and National Power six Class 59/2s. Foster Yeoman and Amey merged their rail concerns into Mendip Rail, and the rail interests of National Power were taken over by EWS.
Ultimately EMD's diligence and flexibility in designing and constructing such a small order paid off in opening the way for the later, much larger, Class 66 order. This design uses the same body shell but is internally different.
