Trains between Haywards Heath and Lewes restart today, 19 days after the derailment. Network Rail renewed 500 metres of track and replaced 850 sleepers.
Trains are running again between Haywards Heath and Lewes from the start of service today, Tuesday 1 September, 19 days after the derailment that closed the line.
The replacement buses that have run between Haywards Heath and Lewes since 13 August stop as soon as the trains resume. Network Rail and Southern confirmed the reopening in a joint statement issued at 21:23 on Sunday 31 August.
Southern says the line reopens “in time for the start of the new school term”. It is asking passengers to check before they travel, because journey planners were still being rebuilt over the weekend.
What was rebuilt
This was not a repair. Engineers took out the damaged railway and put a new one back. Network Rail’s notes to editors record the following work:
- 500 metres of track renewed, laid using a rail drop train
- 850 sleepers replaced
- across a section of embankment 160 metres long
- 9,000 tonnes of Type 1 aggregate delivered to the site
- 250 site trips by tipper trucks
- four engineering trains used to move materials
- at least 5,000 hours of work by Network Rail, GTR and their contractors
All eight carriages were recovered and removed from the site. Specialist Kirow cranes were brought in to lift the derailed vehicles, and temporary foundations and working platforms had to be built first so the heavy lifting equipment could stand safely on the embankment.
Network Rail says the site itself made the job harder. The derailment happened close to the River Ouse and inside what it describes as a sensitive environmental area, which required coordination between engineering, environmental and operational teams.
Before any passenger train ran, the route went through what the company calls a rigorous programme of engineering checks and safety assurance, including test trains.
The investigation is not finished
Reopening the line settles the timetable, not the cause.
The Rail Accident Investigation Branch has published nothing further since its preliminary statement of 19 August, read again today. That statement recorded that forward and rear-facing CCTV from trains using the line earlier on 13 August showed a track geometry irregularity on the immediate approach to the point of derailment, and that RAIB had since received several reports of rough riding at that location.
RAIB has not reached a conclusion. Its investigation is independent of the rail industry and of the regulator, and it will report separately.
The 14:24 London Victoria to Eastbourne service derailed at about 15:54 on Thursday 13 August, roughly a mile north of Lewes station. The rear three carriages came to rest on their sides. Around 150 people were on board, 30 were injured and 20 needed hospital treatment. We set out what investigators had established at that point in our report on the closure.
Lucy McAuliffe, Sussex Route Director for Network Rail, said her thoughts remained with everyone affected, “including those who were hospitalised, and their loved ones”. Jenny Saunders, Customers Services Director for Greater Thameslink Railway, thanked passengers for “the patience, resilience and understanding they have shown while this work has taken place”.
What it means for you
If you travel from Haywards Heath, Burgess Hill or Wivelsfield towards Lewes, Eastbourne or Hastings, this is the position today:
- Direct trains south of Haywards Heath are running again. The replacement buses to Plumpton, Cooksbridge and Lewes have stopped.
- Check your specific train before you leave. Southern says journey planners are still being updated, so the app may not yet match what actually runs.
- Ticket flexibility has ended. Southern’s rule allowing travel two hours either side of a booked train applied to tickets dated up to and including Monday 31 August, according to its service update page, read today. If you hold an unused ticket from the closure period, apply to the retailer you bought it from. You have 28 days after the ticket expires to claim.
- If your train was delayed 15 minutes or more, Delay Repay is the route, not a refund. You can claim one or the other, not both.
Two other Southern changes started today, and neither affects Mid Sussex stations. Network Rail has imposed temporary speed restrictions on the Arun Valley and Uckfield lines after the hot, dry summer, so Southern is running a reduced timetable on both, from Tuesday 1 September until further notice. Some Uckfield line trains are replaced by buses between Crowborough and Uckfield, and London to Portsmouth Harbour passengers now change at Barnham. If your journey goes beyond Sussex on either of those routes, allow extra time.
We track the closures and diversions that do affect Mid Sussex on our roadworks and travel page, and the Brighton Main Line timetable on our trains to London page.
