The 10th anniversary of the train crash at Potters Bar that killed seven people will be marked today by memorial services across Hertfordshire.

On May 10 2002 the London to King's Lynn train derailed as it came into Potter's Bar station due to a set of faulty points. The six passengers killed on the West Anglia Great Northern express were in the train's fourth carriage which became airborne after derailing and ended up wedged under the canopy on a platform at Potters Bar station. The seventh victim, 80-year-old Agnes Quinlivan, was killed by falling debris as she walked close to the station.

Friends and relatives of the victims are among those attending the services.

The first takes place at a memorial garden close to the scene of the crash and includes the laying of flowers and a minute’s silence at 12:56pm – the time the train derailed.

Last year Network Rail accepted liability for the crash and was fined £3million. RMT, The National Union of Rail, Maritime and Transport Workers have said that the ten-year anniversary should be seen as a "wake-up call" to the government and they should reconsider planned cost-cutting measures.
