Question

The 2014 TfL Business Plan says, 'We are currently investigating further capacity and service improvements that can be made to the Northern line beyond our current plans". Will you be investigating splitting the line at Camden Town? Do you believe it will be achievable?

The Northern line is currently undergoing a massive programme of transformation, with plans to increase the service frequency on the Northern line to up to 36 trains per hour over the coming decade.

The signalling system has now been modernised, delivering 20 per cent more capacity on the line with a frequency of up to 26 trains per hour on the Bank branch during the busiest time. TfL is procuring 50 additional Northern line trains and extending the line to Battersea, which will enable a new service pattern partially splitting the line at Kennington. This will bring the line frequency of up to 30 trains per hour, comparable to the service level of the Jubilee line today. TfL must also rebuild key interchange stations: Tottenham Court Road is well underway and there are plans to increase much needed capacity at Bank, Elephant & Castle and Camden Town. 

Once this work is complete - sometime in the 2020s - TfL could then change the service through Camden Town station through full separation of the lines to run up to 36 trains per hour on the line at the busiest times. This would mean a total of almost 50 per cent more capacity compared to today.

This option will remain under review as the transformation of the Northern line progresses, but there is no provision for it within TfL current business planning period up to 2021.
