Police were called to search Lynn’s railway line after a person was almost hit by a train near the town’s station at the weekend.
Dozens of people were on board the 8.44pm First Capital Connect service from London Kings Cross on Saturday when the incident happened close to the Tennyson Avenue level crossing at around 10.25pm.
One passenger reported that the four carriage train, which he estimated had been carrying at least 50 passengers, came to a sudden halt just before the crossing and remained stationary there for several minutes.
He said: “After the train moved off, the driver came on and said, ‘Apologies for the sudden stop back there. We just had someone decide to walk in front of the train’.”
A Norfolk Police spokesman said their officers were alerted to the incident at around 10.40pm.
She said they were told that a woman had been trespassing on the railway and had headed towards The Walks. The area was searched but no-one was found.
However, train staff were warned to be cautious going through the area.
A First Capital Connect spokesman said incidents of that kind were very rare on the rail network.
