Southern Rail: Communication systems issue blocks rail lines across Sussex

Southern Rail reported at 3.57pm on Wednesday, May 6 the issue had occurred between Brighton and Worthing.

The train operator reported a driver on board a train activated the emergency alarm communication system following an egress on board their train, which then developed a fault.

"This system is an important safety feature, and any fault must be investigated before the train can continue with its journey,” a Southern Rail spokesperson said.

"Southern are working to return to their scheduled timetable, but please continue to check journey planners and station information boards before you travel. Some trains in the area will still be disrupted, and may be amended to terminate earlier or start later in their journey than usual.

“You may need to wait longer for a train towards your destination, or change trains more times than usual, which will extend your travel but up to 30 minutes longer than usual.”

Disruption is expected until 6pm.
