The need for further rail capacity in London is clearly identified in the Mayor's Transport Strategy and one of the highest priorities in the medium term is to increase capacity on the West Anglia Routes (MTS proposal 8).
I am aware that TfL are working with the West Anglia Routes Group, the boroughs and the Department for Transport on a number of initiatives, including the West Anglia Main Line Improvements, the Greater Anglia refranchising and the input to the High Level Output Specification for the next Control Period (2014-2019).
However could the Mayor please: a) Outline his understanding of the implications of the recent Comprehensive Spending Review on the proposed four-tracking of the Lee Valley Line, particularly for the section beyond Tottenham Hale;
b) Indicate whether he feels that there are any realistic short term time-tabling changes that could to introduced to enable a minimum four train per hour service to be provided at key stations, such as Ponders End, Brimsdown and Enfield Lock;
c) Advise whether he believes there to be merit in a phased approach to infrastructure provision and, in particular, whether he would support the development of an intermediate option involving a local third track to by-pass Copper Mill Junction which could allow a four train per hour service between Stratford and Tottenham Hale, as well as other local stations to the north;
d) Confirm that TfL will continue to have the resources to work with the Boroughs and other key stakeholders to ensure that a four train per hour, metro-style service can be delivered for local stations in the Upper Lee Valley?
