Mark Thurston, who began his career in the rail industry over 30 years ago at TfL, has previously held positions at The Nichols Group and Metronet.

Since 2008, he has worked with environmental and engineering consultants CH2M and was involved in the London 2012 Olympics and Crossrail projects.

He is currently the regional managing director of CH2M’s European operations, which includes those in UK.

Mark, who replaces interim CEO Roy Hill, said: “HS2 is arguably the most important investment in infrastructure in the UK for a generation, which will serve businesses and communities across much of the country.

“I am looking forward to leading the HS2 team and its partners to deliver a railway that will transform connectivity between our major cities and regions.”

David Higgins, chairman of HS2, revealed that the board believed Mark had the knowledge, experience and leadership qualities to deliver the project within the budget.

“Mark not only knows the UK rail industry from the bottom up, but has worked for organisations operating at the highest level globally.

“His grasp of how to manage the transition from page to reality makes him not only the right person to take over at HS2 as we are on the verge of Royal Assent, but also to see it through the years leading up to the first train being commissioned.”

Mark will start his new role in the spring once he has transitioned his leadership responsibilities at CH2M.
