This route was launched on May 28, 2000 as a
Stagecoach Express service between Northampton and Peterborough. In April 2004, the route extended from Northampton through to Milton Keynes. Over the years, the X4 route has linked the main towns of the county of
Northamptonshire with Milton Keynes and Peterborough enabling better east-west county public transport links than has previously been possible. Initially Stagecoach X7 ran between Northampton and Milton Keynes instead (as well as to and from Leicester), but this was also cut back leaving the X6 as the main link between the two towns. The X4 inter-urban bus service benefited from £4.4 million
ODPM Growth Area Funding between 2003 and 2006 and has seen annual passenger numbers rise from 325,000 in 2003/04 to over 500,000 in 2004/05.
