Green Signals
Green Signals is a show about railways - its politics, its economics, its people and history. We turn over the issues of the day and talk to the people making the decisions that affect all our lives. We also dig into many of the amazing events in the history of an industry that spans nearly 200 years. Nigel Harris (former Managing Editor and Events Director of the leading industry and opinion forming magazine RAIL) and Richard Bowker (former Chair & CEO of the Strategic Rail Authority) steer the show to make it sometimes controversial, frequently irreverent - but always topical and relevant.
