The London Assembly has welcomed Network Rail and Transport for London's decision to launch a consultation on the proposed route for the Crossrail 2 development.
Members of the group's Transport Committee think the project will be hugely important to London's future, but it must be done right.
Mayor Boris Johnson urged the public to air their views on the scheme between now and August 2nd 2013 and he believes Crossrail 2 will revolutionise the capital's transport infrastructure.
Chair of London Assembly's Transport Committee Valerie Shawcross said it is vital that the plans are "robust" and help to regenerate parts of London that need it the most.
"[We] will be carefully scrutinising the plans of those in charge to make sure that London gets the boost it deserves from this proposed new transport infrastructure," she remarked.
All being well, the project could be in operation by 2030 and it will follow on from the impressive Crossrail development, which is currently being built in the capital.
