Can you tell me more about the incident?
Earlier this morning a trespass incident was reported in the Thornton Heath area, and trains were stopped for safety. Emergency services and Network Rail have attended and removed the person.
Trespassing on the railway is extremely dangerous. Trains run at all times, often without warning, and many areas have high-voltage third rails, steep drops, and other hazards.
There are also electrical systems and cables, slippery surfaces, steep drops and other hazards.
Network Rail manages the railway infrastructure, and they're working hard to educate everyone about these dangers and prevent people from accessing the track.
As well as the dangers, trespassing on the railway is also illegal, and obstructing the railway can carry severe penalties.
