Ways to pay for a new rail service linking south west and north east London have been published.

A report by consultancy firm PreicewaterhouseCoopers set out ways to fund Crossrail 2, which will run through Enfield and Haringey.

Options draw on methods used to pay for Crossrail 1, and include paying back investment through a combination of revenue generated through fares, continuing a supplement on business rates and a charge levied by the Mayor of London for community infrastructure on developers.

Other funding options include council tax contribution arrangements that were introduced to help fund the 2012 Olympic Games as well as potentially increasing the community infrastructure levy charged by the Mayor of London.

Money could also come from property-related developments and landowners next to the line.

The study estimates that the total cost of the scheme could be around £27 billion, which includes a fleet of new trains and a variety of additional railway works.

It shows that more than half the cost could come from existing sources.

Mayor of London Boris Johnson, said: “London’s population is growing rapidly and with more people travelling in our city than ever before it’s vital that we deliver extra rail capacity to support future growth.

“Crossrail 2 is an essential infrastructure project and this report shows the range of financing initiatives we could employ to get it moving.”
