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. We'll get you moving as soon as possible. We're aware of your location, and teams 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.
Ticket acceptance on alternative routes:
If needed, Southern and Thameslink will be working with other public transport companies to make sure that your ticket will be accepted on alternative routes.
If you can use another option for your journey, we'll let you know the details here.

Can you tell me more about the incident?
Your train is being delayed because of an emergency radio broadcast being made in this area, reporting a person on the track.
In this case, we've needed to stop trains 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.
Network Rail manage the railway infrastructure, and they're working hard to educate everyone about these dangers and prevent people from accessing the track. You can see their latest safety campaigns here.
As well as the dangers, trespassing on the railway is also illegal, and obstructing the railway can carry severe penalties.
