To provide it with a fleet of locomotives for use on diversionary services during the West Coast Mainline upgrade and rescue duties, Virgin signed a deal with Porterbrook in March 2002 to rebuild twelve Class 47s as Class 57/3s with the first delivered in June 2002. After it was decided they would operate daily services along the North Wales Coast to Holyhead, another four were ordered from Porterbrook. Following the completion of the West Coast Main Line upgrade in 2008 their use fell and after being sublet to Arriva Trains Wales, Colas Rail and First GBRf, six were returned to Porterbrook in August 2011, three in April 2012 and the remaining seven in December 2012.
