The Crown Prosecution Service today advised that no charges should be made over the Paddington Rail crash, in which 31 people were killed.
The CPS told the British Transport Police that further investigation would not be justified.
The service had investigated the training of the driver of one of the trains involved in the accident two years ago as well as the actions of staff in a signal box and the track and signal layout in the approach to Paddington station in west London.
Martin Mimms, a spokesman for the Paddington Survivors Group, said : "I think survivors were prepared for no charges to be made. They are not interested in retribution."
Anthony Beeton, 47, of Wheatfields, Didcot died in the crash. David Taylor, 35, of Abingdon Road, Didcot, and Tony Jasper, of Ashfields Close, Wantage, survived.
The Oxford Mail campaigned for a charge of corporate manslaughter to be brought against the companies involved.
The CPS decision covers senior executives at Railtrack as well as the company itself, which recently went into administration.
