Since joining Network Rail in August 2018, Andrew has refocussed Network Rail to be on the side of passengers and freight users; that is easy to engage with and is an efficient and dependable partner; a company people are proud to work for; instinctively recognised as an industry leader.

This new structure sets Network Rail up for deeper devolution and to be more responsive to the needs of train operators, passengers and freight users by bringing Network Rail’s 43,000 employees closer to those we serve.

Prior to joining Network Rail, Andrew served as Chief Executive of the Civil Aviation Authority from 2009. This followed a wide-ranging career in the rail industry, which included roles as Managing Director of South West Trains, and Managing Director of the Rail Division for First Group plc.
