Tube Lines has signed a two year renewal deal with Capgemini for running its IT infrastructure.

The company, which maintains the Jubilee, Northern and Piccadilly lines on the London Underground, has worked with Capgemini for the past five years.

It has cut 25 per cent from IT costs since 2007, through a VMware virtualisation project alongside other system changes. A desktop software refresh completed this year saw it update its 3,000 machines from Microsoft Windows XP to Vista.

The company also uses Microsoft Windows Server 2008 software - having moved from Server 2003 - as well as Microsoft Sharepoint and Microsoft Office Communications Server. It uses Oracle middleware and the IBM Maximo asset management system.

“IT underpins the services we provide and simply has to work well if the current massive investment in London Underground infrastructure is to deliver the major improvements that our customers and passengers expect from it,” said Adrian Davey, head of IT at Tube Lines.

End-user satisfaction in support services was twice as high as prior to outsourcing in 2005, he claimed.
