In March 2007 Northern Rail announced it would be acquiring a further 30 Class 158s from Arriva Trains Wales, Central Trains and First Great Western to replace 26 Class 142 "Pacers". Northern Rail ended up only receiving 19 Class 158s, but did gain eight centre carriages from East Midlands Trains in 2008 that were inserted into Northern's ex First North Western Class 158s. Twelve Class 142 "Pacers" were placed in store but reactivated by the end of 2008 when they were sublet to First Great Western from December 2008 and the balance returning to service with Northern.
