Network Rail, as the successor to Railtrack, was last week fined £3 million and ordered to pay costs of £150,000 following a prosecution brought by the Office of Rail Regulation (ORR) for a health and safety offence which caused the Potters Bar derailment.
Seven people were killed in the incident, with many more seriously injured.
A Network Rail spokesman said:
“This week marks the ninth anniversary of the terrible, tragic event at Potters Bar. We recognise for many that the sorrow remains and we should all pause and reflect as we remember those who lost their lives.
“Network Rail has today been sentenced for failings that contributed to this accident and we accept the fine as we accept the liabilities inherited from Railtrack. We say again today that we are truly sorry.
“Private contractors are no longer in control of the day-to-day maintenance of the nation’s rail infrastructure since Network Rail took this entire operation in-house in 2004.
“Today the railways are safer than they have ever been, yet our task remains to build on that record and always to learn any lessons we can to make it ever safer for passengers and those who work on the railway.”
