Virgin Trains is continuing to outsource its core IT infrastructure with the extension of an agreement with Capgemini for another three years.
The agreement, which is worth millions of pounds, will see the relationship reach at least its 14th year.
Capgemini manages systems on 100 servers in Capgemini datacentres in Yorkshire. These include financial systems as well as operational applications such as crew scheduling and rostering.
About 1,000 workers in 42 locations receive desktop and laptop management and support services from a team at a Capgemini service centre in Inverness.
Virgin Trains said it considered other bids but decided to keep Capgemini on board.
Capgemini recently carried out a desktop and laptop environment refresh at Virgin Trains. This involved a installing new hardware and migrating from Lotus Notes to the latest versions of Microsoft Exchange and Microsoft Office.
Francis Jellings, head of IT at Virgin Trains, said the contract has changed over the years. "The service has changed from being more reliant on people to using automated services."
He said you have to work closely with your supplier to allow this type of re-modelling of contracts to work. The contract was written about three years ago and the new deal will see a continuation of this.
