Can you tell me more about the incident?
A trespass incident was reported in the Mitcham area.
In this case, we had to stop trains entirely, as it was not safe to run services past the person. Emergency services and Network Rail responders have attended, and the person has been safely removed from the railway.
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.
