Rail commuters are being warned to get ready for what's been billed as the "biggest timetable shake-up in rail history".
Train times on the Govia Thameslink Railway network will be changed from Sunday May 20, and many passengers have been told to expect their trains to start and terminate at different stations.
As part of the alterations, there will be more frequent trains from Bedford and Luton into London, as well as double the amount of seats on some morning peak services from Cambridge to the capital.
"We don’t want passengers to get caught out and so we strongly advise them to look up the times of their trains as they will find that from 20 May each and every one of them has changed," Charles Horton, Govia Thameslink Railway Chief Executive, said.
“Due to the sheer scale of the changes, we will have to redeploy a large number of trains and crews and services may not run at normal times during the introductory phase, although the impact on peak time services during the transition will be minimal.”
“Introduction of the new timetables is a major milestone in the delivery of RailPlan 20/20, our programme to modernise rail services, taking advantage of the new infrastructure and trains provided by the Government’s £7bn Thameslink Programme.”

Despite the optimism from Govia Thameslink Railway, the RMT union insists the new timetable could have "disastrous consequences".
“The planned new timetable on GTR will place massive additional strains on infrastructure and staffing levels that are already struggling to cope with current capacity," General Secretary Mick Cash said.
"The company are winging it with potentially disastrous consequences. Instead of trusting them with a new timetable they should be stripped of the franchise to make way for an integrated, publicly owned operation that is properly equipped to deliver these services.”
