 This locomotive had originally been purchased by the Foster Yeoman group (along with its sister locomotives 59001/002/004/005), these being the first privately owned locomotives to operate under British Rail.In 2015 it was confirmed a further seven Class 66s would be purchased.Even though the locomotive type no longer conforms with emissions regulations, GBRf had purchased some spare EMD 710 engines, shipped them to the United Kingdom before the 31 December 2014 deadline and then returned them to the United States for fitting to the new locomotives to be delivered in 2016.
