Interesting that you say it's all on the driver's head, as this driver's widow has complained about the reporting of this derailment (particularly the BBC) which she says has only taken parts of the initial RAIB report, whilst leaving some details out, making it sound like the driver was at fault. She has said that he was driving completely in accordance with his instructions.
