Following earlier trespassers on the railway in the Amberley area all lines between Horsham and Barnham have now reopened.

Until service returns to normal, trains running between these stations may still be cancelled, delayed by up to 30 minutes, revised or diverted.

This issue is expected to continue to impact services until 17:00.

Customer advice:

Services can now run in both directions again between Horsham and Barnham. Southern services that run between Bognor Regis / Portsmouth & Southsea and London Victoria may however have been delayed, cancelled, revised, or where possible diverted via an alternative route.

Please check before you travel this afternoon. it is advised that you allow plenty of extra time - at least at extra 20-30 minutes, and you may need to use an alternative route or change trains in order to complete your journey.

Tickets will be accepted for no extra cost on the following:

• Southern services on any reasonable route including between Littlehampton and London Victoria, and between Portsmouth / Bognor Regis and Brighton
• Thameslink services between Brighton and London, and between Horsham and London
• Stagecoach bus route 9 between Arundel, Littlehampton, Worthing, Lancing and Shoreham-by-Sea

If you're waiting on a train which is delayed between stations:

If your train is delayed between stations, please remain where you are and listen to announcements, or speak to staff for further information. Teams will get you moving as soon as possible. They are aware of your location, and will be doing everything they can to help you continue your journey.

Please don't leave the train unless you are asked to do so. Other trains may still be moving in the area, and the track is also a very hazardous environment. In areas where the trains are powered by an electric third rail, this usually stays live and dangerous during incidents, and looks the same as other rails.

Can you tell me more about the incident?

A trespass incident has been reported between Horsham and Barnham.

In this case, trains have needed to be stopped entirely, as it's not safe to run services past the person. Emergency services and Network Rail responders are attending to make sure the person is removed.

Trespassing on the railway is very dangerous. Trains run all day, every day - whether passenger trains, freight trains or specialist engineering work machines. It's not possible to be sure that you can hear when a train is coming, and in many cases, you won't see a train until it is very close to you.

In many areas, trains are powered by an electric third rail, which carries a dangerous electric current. There are also other electrical systems and cables, slippery surfaces, steep drops and other hazards.

As well as the dangers, trespassing on the railway is also illegal, and obstructing the railway can carry severe penalties.
