Strategic Route 7 - Great Eastern is the designation given by Network Rail to a grouping of railway lines in the East of England that encompasses the Great Eastern Main Line and its various branch lines. The route services the regional centers of Colchester, Ipswich and Norwich as well as the ports of Felixstowe and Harwich. [1]

As part of Network Rail's Strategic Business Plan a Route Plan for each route, including Route 7, is published annually. The Route 7 plans for 2008[2] and 2009[1] are made available online.
Together with Route 5 - West Anglia and Route 6 - North London Line and Thameside the route is included in the Greater Anglia Route Utilisation Strategy.[1]
The Greater Anglia RUS includes a number of proposals for the future development of the route. In the medium term, 2009-14, this includes minor infrastructure works and additional rolling stock to allow main line peak-service trains to be extended to 12-car formation. Also included is the proposal for the extension of platforms at Stratford to handle 12 cars, to allow all main line peak-service trains to be extended to 8 or 12-car formation. In the longer term intentions are to continue the lengthening of peak trains to 12-car formation.[3] Enhancements to the power supply of the route are intended for completion by 2012 to interface with those carried out on Route 5 and Route 6.[4]
