The Government has announced the winner of the competition to run a new rail franchise that includes the £6.5 billion Thameslink project.
The new Thameslink, Southern and Great Northern (TSGN) franchise will be run by the Go-Ahead Group company Govia, with rival company FirstGroup missing out.
FirstGroup had been running a section of the new franchise under the First Capital Connect (FCC) banner since 2006, but FCC will disappear when the new seven-year TSGN franchise starts in September 2014.
While Go-Ahead celebrated today, FirstGroup chiefs expressed their disappointment at losing out on a franchise which, in terms of passengers, is the biggest ever awarded.
