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?
Emergency services are dealing with an incident in the Mitcham Eastfields area.
A trespass incident has also been reported.
In this case, trains have needed to stop entirely, as it's not safe to run services. Emergency services and Network Rail responders are attending to make sure the person is removed and the incident is resolved.
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.
Ticket flexibility:
If your train is cancelled, you will be able to travel on an alternative service operated by any other participating train company, either two hours before or two hours after the original departure time of the cancelled service, in order to reach your destination.
If you decide not to travel or cannot complete your journey due to cancellations, you are entitled to a full refund from your original point of sale.
For further information and guidance please contact your train company or speak to a member of railway staff.
