The main feature of the district is the Milton Keynes Central railway station (an inter-city stop on the West Coast Main Line), one of the five stations serving Milton Keynes. Coach services operate from here as well as from the Milton Keynes coachway next to junction 14 of the M1 motorway. Services include the Stagecoach X5 service that replaces the Varsity Line, which links Milton Keynes with Oxford in the west (for connections to the west and Wales) and Cambridge in the east; and the 99 service to Luton Airport, operated by Stagecoach. The station building houses commercial office lets and food outlets, and the Station Square development includes further office lets and retail outlets.
