Business leaders have staged a protest against the continuing dispute on Southern Railway, warning that the disruption to services is threatening the region's economy.

Dozens of businessmen and women carried banners on the "great train robbery" during the early-morning demonstration outside Eastbourne railway station.

The station is one of many affected by months of disruption because of industrial action, staff shortages and other problems.

Members of the Rail, Maritime and Transport (RMT) union will walk out for 24 hours on Wednesday in a long-running dispute over the role of conductors, while drivers from Aslef have rejected a proposed deal to end a row about driver-only trains.

The protesters said the disruption had cost the area more than £300 million, caused stress and trauma to families and is now endangering the local economy.

Their banners blamed all sides in the dispute, including Transport Secretary Chris Grayling, union leaders Mick Cash and Mick Whelan and bosses of Southern's owner, Govia Thameslink Railway.

Tim Cobb, president of the Eastbourne Chamber of Commerce, said all sides should get together to resolve the issues.

"We are taking to the streets to express our frustration and anger and to urge the company, unions and Government to sort it out.

"We are not pointing the finger at anyone, but everyone should realise the damage this is causing."

Businesses in and around the railway station suffer losses on strike days, while hotels are hit by cancellations because visitors cannot travel, added Mr Cobb.
