A proposed major infrastructure project, Crossrail 2, moved a step forward
today (24 March 2015) as the government published updated plans to protect
land for its route from conflicting development.

Crossrail 2 is a high frequency, high capacity rail line that would run
between south west and north east London. No decision has yet been taken on
its construction, and the Department for Transport is working with
Transport for London (TfL) and Network Rail on a business case, after the
Chancellor made £2 million available to support this work.

....

Michele Dix, TfL’s Managing Director for Crossrail 2, said: "The confirmed
safeguarding marks a vital step forward in progressing Crossrail 2 which is
significant in providing more rail capacity to support growth in London for
the future, in particular up to 200,000 new homes. We’ll continue
developing the scheme reflecting comments received to date with a public
consultation later this year. We are working hard to deliver Crossrail 2 by
2030."

The updated safeguarded route published today, following a 10-week
consultation, extends from Wimbledon in the south-west to Tottenham Hale
and New Southgate in the north-east. It will replace the previous
directions and will ensure new development does not affect the ability to
build and operate Crossrail 2 in the future.

Under the new Crossrail 2 safeguarding directions, relevant planning
applications in safeguarded areas will be referred to TfL for advice. If
development interferes with Crossrail 2, either a compromise will be
reached or the development will not be allowed.

TfL currently has no plans to compulsorily purchase properties along the
route. Any property or land owner who considers they may be eligible for
statutory blight should seek advice or contact TfL.

The government and TfL have made modifications to the proposed safeguarded
route at Wandsworth Common, Chelsea, Soho Square and Angel to allay public
concerns, after carefully considering the consultation responses. The
updated direction will come into effect from today.

Crossrail 2’s route now passes through the City of Westminster, the London
Boroughs of Barnet, Camden, Enfield, Hackney, Haringey, Islington, Merton,
Wandsworth, and the Royal Borough of Kensington and Chelsea.

Among the most significant changes to the previous safeguarded route a

- a new tunnel entrance south of Tottenham Hale station to take the line
from above to below ground

- a proposed extension to New Southgate

- a station connecting to both Euston and King’s Cross, instead of at
King’s Cross only

- an altered route running from Angel to Tottenham Hale and Seven Sisters
via Dalston Junction, instead of via Hackney Central to Epping

- an altered route running from Victoria to Angel via Tottenham Court Road
instead of via Piccadilly Circus

- an altered route running from Wimbledon to Chelsea via Clapham Junction
and Tooting Broadway, instead of via Putney

Safeguarding is a planning process that enables the government to protect
land needed for long term infrastructure projects from developments that
would prevent them being built or make them more expensive. Safeguarding
does not necessarily prevent developments taking place; it ensures that
when they take place the design can accommodate nationally important
infrastructure.
