will go, as will their thoughts and desires and requirements. So it is going to be stressful all the way through.
“One good thing is that all the funders know we will build this railway to deliver what they need, so there is a unity of aim.”

Estimates also suggest that up to 25,000 jobs and 16,000 new homes could also be created following the extension. And journey times from Nine Elms or Battersea to the West End or the City will, in some cases, be less than 15 minutes.
Unity of aim for partners
While waiting for the TWAO powers, Shaw stated that during the construction phase it will be interesting to see how the political landscape evolves.
“Before the project ends, there is the matter of one mayoral election, which could change things, and then there will be one – maybe two – general elections,” he said. “In between there will be lots of people within the GLA who
As well as developing two new stations, TfL plans to build 3.2km of tunnel with a 5.2m internal diameter, including overrun/stabling tunnels west of the terminus at Battersea, a crossover east of the terminus and junctions serving each of the tunnels to link with the existing railway at the Kennington loop.
“It is not quite Crossrail but it is a lot for us,” said Shaw. In addition, NLE will become the seventh part of TfL’s current signalling roll-out on the Northern Line upgrade, which should be finished shortly.
As TfL has previously explained, the NLE is “primarily considered as an extension of the Charing Cross branch”, because:
• Connection for the extension can be made from the Kennington Loop, allowing trains to continue to Battersea, or terminate at Kennington and then return northwards from the loop;
• Charing Cross branch are less crowded (and
forecast to remain so) than the Bank branch; • Charing Cross branch allows for enhanced transport accessibility to Crossrail at Tottenham Court Road as well as the Central line;
• Charing Cross branch enables construction and operation of the NLE with relatively minor disruption to other train services; and • The Charing Cross branch would perform better than the Bank branch in meeting demand to travel from the Vauxhall Nine Elms and Battersea Opportunity Area to the West End and City destinations.
In terms of a full train service, TfL is hoping to have it operational by 2020.
“Once the line is complete you will get about 10 to 16 trains per hour down to Battersea, and then we will do the second part of the extension increasing that number. It really fits in with the overall Northern Line plans,” Shaw added. He was confident that if the ambitious aims of NLE can be achieved, “it will allow us to demonstrate that TfL can be trusted to spend taxpayers’ money wisely – and that we can build things on target and to price.”
