Hillingdon MPs Nick Hurd and Sir John Randall have joined forces with neighbour Dominic Grieve (Beaconsfield) to call for the Government to scrap plans for a spur connecting Heathrow Airport to the HS2 rail line in Ickenham.
The Conservative MPs wrote to transport secretary Patrick McLoughlin requesting a meeting with him to discuss the spur after the Parliamentary summer recess ends on September 1.
Mr Randall also revealed last month that he will be standing down as MP at the next general election in 2015.
In their letter, the MPs acknowledged a previous response from Mr McLoughlin that the Heathrow Spur is not part of the initial preferred route for Phase 2 of the high speed line, calling it “an historic recommendation made by HS2 for which no business case has yet been made.”
Mr Hurd told getwestlondon: “One of my campaigns is to get the Government to drop the Heathrow spur off HS2, this letter is the latest step in that campaign.
“The Heathrow spur is a line on the HS2 map that needs to be removed. No case has ever been made for it.
“There are far better options to connect Heathrow to HS2 if the latter goes ahead. Almost £2billion could be saved and used for more generous mitigation and compensation for residents.
“Scrap the spur and extend the tunnel is my message to the Government,” Mr Hurd said.
If the spur is built it would connect to the HS2 line between the West Ruislip tunnel portal in Ickenham Road and Harvil Road in Ickenham.
The decision on the Heathrow spur was put on hold until after the Davies Commission report on airport expansion is published next year, but a ‘passive provision’ for building the spurs - the junctions where the tracks will connect to the HS2 line - is the reason requests to extend the Ruislip tunnel to beyond Ickenham are unlikely to be agreed.
This is because connections between the spurs and the main line HS2 track could not be sited in tunnels, they would have to connect above ground.
During a trip to Uxbridge in April, Mayor of London Boris Johnson told Ruislip Against HS2 campaigner Lottie Jones the spur would be a “ludicrous waste of money and should be scrapped.”
