The court case begins today. It's because of the company's failure to provide and implement suitable and sufficient standards, procedures, guidance, training, tools and resources for the inspection and maintenance of fixed stretcher-bar points.
The rail regulators prosecution follows the conclusion of its investigation into the derailment of the Virgin Pendolino passenger train, and the completion of the coroner's inquest into the death of Mrs Masson.
On 23 February 2007, the 17.15 Virgin Trains service from London Euston to Glasgow Central derailed on the West Coast Mainline near Grayrigg in Cumbria. 109 passengers were on board. One passenger, Mrs Margaret Masson, was killed. 86 people were injured, 28 seriously.
