Can you tell me more about the incident?
A trespass incident has been reported in the Huntingdon area.
As soon as trespassing is known about, the speed of trains in the area is reduced, as it's not safe to run services at their usual speeds when someone is on the track. Sometimes, trains need to stop entirely. Emergency services and Network Rail responders will be 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.
There are also 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.
