Transport for London has issued a tender to upgrade the singalling for the London Underground ‘Sub Surface Lines’ - the Circle, District, Metropolitan and Hammersmith and City lines.
The contract has been re-tendered following the collapse of failed tube upgrade contractor Metronet, which had originally tendered the contract in 2007.
MHowever, since TfL took Metronet back in house, it has decided that it can achieve better value by re-tendering the work.
TfL expect the contract to boost capacity and reliability by 40% when it operates with new rolling stock.
The contract will be the single biggest piece of work on the Tube, they say.
Managing Director of London Underground Richard Parry said: “We’re investing billions to transform the Tube. This new Sub-Surface lines signalling contract will, when complete, deliver huge increases in capacity and reliability, to provide our customers with the service they need.
“The original contract that we inherited from Metronet was over-priced and incompatible with other signalling systems on the Tube network. By re-tendering, we have saved London’s fare and taxpayers millions of pounds, ensuring London will get the transformed Tube it needs at the best value for the public purse.”
London Underground say they have saved some £2.5bn through the renegotiation of contracts, changing the upgrade programme, and improving procurement and operation.
Mayor of London’s Director of Transport policy, Kulveer Ranger, said: “We will all notice as new trains start to roll out on the Tube, but equally important to Londoners’ journeys is the renewal of the signalling system, which will allow the trains to carry passengers more quickly and reliably. That we are delivering this whilst at the same time saving many millions of pounds is good news for London,” he said.
