A new railway timetable is being introduced on Sunday, with the industry promising more services, shorter journeys and new routes across the country following infrastructure investment and upgraded carriages.
The changes will include the first non-stop trains between London and Bristol in decades and 1,000 extra services a week, on top of the 4,000 introduced over the past two years, according to the industry body the Rail Delivery Group (RDG).
Train timetables are changed twice a year, in May and December.
The botched change in May 2018 led to chaos, and passenger watchdog Transport Focus said travellers would be hoping for a smoother introduction with the latest changes.
The RDG sought to reassure passengers over the upcoming timetable, stating that the industry has put “years of work into drafting, consulting and planning for these changes”.
Robert Nisbet, the organisation’s director of nations and regions, urged passengers to check their journey details in advance as many times are changing.
He added: “Train operators and Network Rail will be working together to run a reliable service and respond quickly to any teething problems as people get used to the change.”
The launch of the May 2018 timetables saw services crippled in parts of the North and the South East, with blame attributed to Network Rail, train operators and the Government.
Transport Focus chief executive Anthony Smith said: “This time around passengers need the rail industry to deliver a smooth set of timetable improvements – so they can reliably use both new and existing services.
“Many passengers should have a greater choice of services with more seats as result of these changes. However, there will also be some who lose out with fewer or slower services.
“Train companies must have plenty of visible staff on hand to guide passengers, to answer questions on how these changes will affect them, and to explain what travel choices they have.”
Sunday will see the biggest timetable change on the Great Western Railway network since the 1970s, taking advantage of Network Rail’s electrification of the line between London and Bristol, and the operator’s new intercity express trains.
Non-stop trains between London Paddington and Bristol Parkway will have journey times as short as one hour and eight minutes, shaving 12 minutes off the existing quickest services.
Fastest journey times between the capital and Bristol Temple Meads – near the centre of the city – will be cut by 17 minutes to one hour and 19 minutes.
The frequency of trains on this routes will be increased from two per hour to three during the morning and evening peaks.
Major improvements are also being promised on the ScotRail network, with additional services in north-east Scotland and extra seats between Edinburgh and Glasgow.
A new station, Robroyston, will open in north-east Glasgow on the line between Queen Street and Cumbernauld.
Other operators introducing new services are Greater Anglia, London North Eastern Railway, Northern, TfL Rail, Thameslink, Transpennine Express (TPE), Transport for Wales, West Midlands Railway and London Northwestern Railway.
TPE admitted last week that the frequency of its new direct Liverpool-Edinburgh trains will initially be lower than the planned hourly service.
The firm blamed a maintenance backlog and infrastructure problems.
