Timetable information

The previous rail service

For a number of weeks after the timetable change in May, the level of service our Great Northern and Thameslink customers experienced fell far below the standard that we expected to deliver. On behalf of Network Rail, ourselves and the rail industry we apologise unreservedly for this.

It was the biggest timetable change ever and four times bigger than industry processes had coped with before.

We anticipated some degree of disruption to services while we made the huge changes in operational processes that the new timetable required.

However, the impact of the late delivery of the timetable by Network Rail has been significantly more disruptive than we expected and only a few days before launch, it was determined that there was a mismatch between the final timetable and the required route knowledge skills of drivers.

As a result of this disruption, we introduced an interim timetable on Sunday 15th July which is delivering a more consistent and more reliable service.

We still believe that the intended May 2018 timetable will bring huge benefits to you, so once the current interim timetable is bedded in, we will look to introduce more services to complete the intended May 2018 timetable and we will keep you informed at every step along the way. Please be assured that we are doing all we can to bring this about as swiftly as possible.

Again, we apologise wholeheartedly for the issues have experienced across the network since May.

Further Thameslink Monday to Friday services will be brought online throughout September 2018.

Travel advice for passengers

We have now introduced an interim timetable to deliver a consistent and more reliable service. This revised timetable will be in place until we introduce the full timetable, delivering additional capacity, more frequent trains and new routes across the network.

How do I plan my journey?

The interim timetable is reflected in both our own and the National Rail online journey planners. However further late evening and weekend alterations are possible due to engineering work. See below for details.

You can view and download PDF timetables on the timetable page. It is essential that you continue to check your journey online at before traveling on the day of your journey.

Printed copies of the timetable are also available now from staffed stations, however ‘Train times’ posters will be updated in the coming weeks.

Please always check your journey before you travel if you are travelling overnight and at weekends when engineering work may take place. These alterations may not be reflected in journey planners until 20.00 on the day before the service operates. A list of planned engineering work is shown here.

What alternative routes are available?

Arrangements for Strood and Higham customers

All tickets for journeys between Higham/Strood and London can also be used on Southeastern High Speed services between Strood and London St Pancras. Buses will operate between Higham and Strood to connect with High Speed services. Please use the on-line journey planner to plan these journeys.

What are you doing to fill any remaining service gaps?

Ticket acceptance with other operators will remain in place where it is still required as listed above. Replacement buses may operate on some routes so please check for information on the current arrangements.

The primary focus of Great Northern, Thameslink and our industry partners since 21 May has been on creating a timetable that will provide customers with a reliable and robust train service.

Some stations will unfortunately see a reduced service from 15 July. We are sorry for this, but we can assure you that every effort is being made to restore the full May 2018 timetable. Until that time we will continue to add in services when we are able to do so.

In order to achieve a consistent service, special stop orders (arranging for a train to stop at a station it is not scheduled to, often at short notice) will not be issued other than during times of disruption or if there is a particularly large gap in service.

Are you continuing to support passengers who require assistance?

Passengers travelling with accessibility requirements can still expect the same level of assistance and support from our staff as before. Our travel policies have not changed - we continue to recommend that customers contact us the day before travel if they are pre-booking their assistance.

Passengers can however continue to travel without booking assistance. It is their choice. Passengers can contact our Assisted Travel team if they want advice before they travel.

On some routes, trains will be busier than normal at peak times. If you have the flexibility to travel outside of these times you may wish to alter your plans.

We recommend that all passengers continue to check before they travel.

More detail is available on the assisted travel pages:

How long will this interim timetable be in operation before the full timetable promised for May is introduced?

Once this interim timetable is bedded in, we will look to introduce more services to complete the intended May 2018 timetable and we will keep you informed at every step along the way.

Why do the changes disproportionately affect off-peak trains or remove a service that was running until 14 July?

We have adjusted our resources to ensure trains operate at times that benefit the largest number of customers and proportionately, more off-peak services have been removed from the interim timetable. We hope to minimise the impact by advertising these changes in advance and providing alternatives where possible.

Will there still be shorter trains?

We aim to run all trains with the maximum number of coaches possible, however the length of trains may be restricted by the physical constraints of the route they are operating on e.g. platform lengths.

Are all your drivers trained now?

The training of drivers is continuing, however we are confident that the current resource will allow us to operate the timetable we are now advertising.

Is first class no longer available to holders of standard class tickets?

Standard class ticket holders will no longer be able to use first class, except when advised otherwise by our station or on train staff.

Can I now rely on the information screens at the station?

The interim timetable provides a stable service that is fully uploaded into industry systems. It will therefore be reflected correctly on station screens.

Can I now reliably plan my journey in advance at or should I still check before I travel?

The interim timetable is fully uploaded into industry systems and therefore will be correctly reflected in journey planners in advance. Once this interim timetable is bedded in, we will look to introduce more services to complete the intended May 2018 timetable. Additionally, any alterations because of engineering work will be uploaded progressively on a week by week basis. Therefore, we advise that you continue to check your journey before you travel.

Will alterations because of engineering works be reflected in the journey planners in advance?

If you are travelling overnight or at weekends, information on engineering work alterations may not be available until 20:00 the day before the service operates. We will add a message on journey planners to any services that we expect to be altered by engineering work until journey planners are updated to reflect this, and in these cases you should re-check your journey before you travel.

Will existing ticket acceptance still be in place from 15 July?

Ticket acceptance will remain in place until further notice as listed further up this page.

A background to the changes

What did you need to change the timetable in the first place?

Demand for rail services have doubled in just 16 years on the Govia Thameslink Railway network and 12 years on Southern routes into London. While this has been very welcome, it has also brought its challenges and some of our busiest routes are operating at capacity, particularly during peak times. To facilitate the extra services to satisfy the huge growth in demand, the railway is undergoing its biggest modernisation since the Victorian era. And the new timetable, introduced on Sunday 20 May, was planned to be the most ambitious in recent railway history, providing additional capacity for 50,000 more peak-time commuters into London.

In order to make space on the network for hundreds of extra services, the timing of all GTR services had to be changed. All of these new journeys needed to be individually approved by Network Rail to ensure the national rail network runs safely and smoothly. Unfortunately, as a result of the sheer number of changes required and the late running of some engineering improvements, the process took longer than anticipated, approvals for service changes were delayed and some timetable requests were changed.

This meant that Govia Thameslink Railway (GTR) had much less time to prepare for the new timetable which required trains and drivers to run on different routes. The differences between the timetables submitted and those approved created a requirement for training that had not been anticipated. This meant that the necessary specialist training was not able to be completed in time for drivers to learn new routes and for GTR to address all the logistical challenges.

Why didn’t you delay the changes?

The new timetable had to be implemented because it is an integral part of a UK-wide rail plan, dovetailing with other train operators’ timetables as well as future engineering schedules.

What are you doing to put this right?

We fully understand that passengers want more certainty and we are working very hard to make changes that this week should bring greater consistency to the timetable with fewer unplanned cancellations. This will minimise service gaps wherever possible and allow passengers to arrange their journeys with greater confidence.

This means passengers will be able to plan journeys ahead of time although they are still advised to check for any alterations that have to be made on the day of travel.

We will also be working with industry colleagues to establish a new temporary timetable that will progressively deliver improvements.

Have you got enough drivers?

We have enough drivers. The significant delay in Network Rail agreeing the timetable has directly impacted our ability to re-work train crew schedules, work locations and some new route training.

Why did you continue to promote the new timetable and not advise of the issues before the 20 May?

The implications of having only just over two weeks to prepare a plan rather than three months meant that the full impact of the timetable was not known until it was introduced. We had to implement the new timetable because it dovetails with other train operators across the country and future engineering work.
