The Department for Transport sets the overall framework for Govia Thameslink Railway’s (GTR’s) timetables, including minimum numbers of services at each station as well as maximum journey times for key routes. The timetable changes that are being implemented from May 2018 in order to deliver the benefits of the Government’s £7bn investment in the Thameslink Programme, have been developed with the rail industry over a number of years.
These changes were set out in GTR’s consultation, which took place in three stages in 2016 and 2017. It was one of the largest consultations to have taken place on the railways. The reason for the change is to maintain a consistent pattern of services during the peaks. While we appreciate that some passengers would prefer being able to choose between Southern and Gatwick Express services, this consistent calling pattern should bring more reliable and resilient service performance in the long term. Overall, the timetable has been designed by GTR to benefit the maximum number of its passengers.
