In her new book 'Off the Rails: the Inside Story of HS2', Sally Gimson meets with the politicians, engineers and ordinary people affected by the failure of HS2. Travelling from demolished council estates in Camden to ghost towns along the now cancelled northern branch, Off the Rails provides a forensic examination of how a vital social project imploded. Christian discusses in depth with the author the insights gained from her research, the lessons that the UK should learn and what needs to be done to bring the truncated project into service.
