Lewes to Haywards Heath line shut for at least ten more days as crane recovery of derailed carriages begins
By Staff Writer | 17 August 2026
Network Rail says the railway will stay closed while two 125 tonne rail mounted cranes lift away three derailed carriages and engineers assess the damage beneath them. Twenty people were hurt, two of them seriously, when a Southern service left the track near Lewes on 13 August.
The railway between Lewes and Haywards Heath will remain closed for at least another ten days, Network Rail said on Sunday, as a recovery operation begins to lift three derailed carriages clear of an embankment near Lewes and to establish what it will take to rebuild the line beneath them.
The Southern service from London Victoria to Eastbourne derailed on the afternoon of Thursday 13 August with around 150 people on board. Three carriages left the track and slid part of the way down the embankment, and British Transport Police declared a major incident. Two passengers were taken to major trauma centres with injuries the force described as severe but not life threatening, and a further eighteen people treated in hospital have since been discharged.
Our thoughts remain firmly with those who were injured and their loved ones. On behalf of BTP, I wish them a full and speedy recovery.

The Rail Accident Investigation Branch completed its work at the site on Saturday and has handed the railway back to Network Rail. Its investigation into the cause of the derailment continues, and nothing has been published on that question. The site itself is now an engineering problem, and a hard one.
Two 125 tonne cranes, and ground that must first prove it can carry them
Engineers are preparing the site for two 125 tonne rail mounted cranes, among the largest available for use on the railway. Before any lift can begin, teams must satisfy themselves that the ground and the remaining track are stable and strong enough to support both the cranes and the weight of the carriages they will carry.
The location works against them at every turn. The railway sits close to a river, inside a Site of Special Scientific Interest, and the only road access runs through a residential area. As much of the specialist equipment as possible is being brought to the site by rail, given the difficulty of access by road. Network Rail says it is working with Lewes District Council and engaging with residents while the work runs alongside homes and protected land.
The repair cannot be scoped until the load is off
Only once the carriages have been removed will engineers be able to assess the damage to the railway in full and understand the scale of the repair needed before services can resume. The closure estimate is therefore a floor rather than a programme: ten days covers the recovery, not necessarily the rebuild.
This is a complex recovery operation in a very difficult location, and our teams are working hard to recover the carriages and repair the railway, to resume services safely as soon as we can.
Lucy McAuliffe, Sussex Route Director, Network Rail
Ms McAuliffe added that teams were working around the clock and that further updates would follow as the recovery progresses.
While the line is shut, replacement buses are running between Lewes and Haywards Heath, serving Cooksbridge and Plumpton, and passengers for other stations are advised to travel via Brighton. Tickets are being accepted on alternative Southern, Thameslink and Southeastern services.
For engineers the job is a plain illustration of what recovery work means when the constraint is not the lift but everything around it: prove the bearing before the crane arrives, bring the plant in by rail because the road cannot take it, and leave the damage assessment until the load is off. The questions that matter most, why the train left the track and what the rebuild will cost, both wait on work that has not yet begun.
