The BML2 Project Group has produced its own appraisal into how more capacity, network expansion and boosting the regional economy can be achieved in the South East. As well as reopening BML2, the group suggests creating a second North-South route in London through Canary Wharf and Stratford.
Network Rail will be publishing its own appraisal of route capacity shortly. Other proposals to relieve the Brighton Main Line when it is blocked have included opening the Arundel Curve.
