A railway line in East Sussex will remain closed for at least 10 days [1] following the derailment of a Southern Rail train.

The prolonged closure disrupts travel between Lewes and Haywards Heath while crews work to remove the wreckage and repair damaged infrastructure.

The incident occurred Thursday afternoon near Lewes [2]. A Network Rail spokesperson said two passengers were seriously injured [3]. Around 150 people were on board the train at the time of the accident [4].

Network Rail and Southern Rail issued a joint statement confirming that the line will remain closed for at least another 10 days [1]. The closure is necessary to allow for the recovery of the eight-carriage train, and to carry out essential track repairs [5].

Recovery operations began shortly after the derailment to stabilize the site. Officials said the priority is the safe removal of the carriages and the restoration of the line to ensure future safety.

"The line will remain closed for at least another ten days," the joint statement said [1].

Emergency services responded to the scene Thursday to treat the injured and evacuate the remaining passengers. The specific cause of the derailment has not been detailed in the current recovery updates.

The line will remain closed for at least another ten days.

The extended closure indicates significant damage to the permanent way or complex recovery challenges involving the eight-carriage set. This disruption forces a reliance on alternative transport for commuters in East Sussex and highlights the vulnerability of regional rail bottlenecks during infrastructure failure.
