HS1 Ltd has appointed senior rail boss Dyan Crowther as chief executive.
Crowther, currently chief operating officer at under-fire rail services firm Govia Thameslink, will join the company operating the rapid link from London to the Channel Tunnel in January 2017.
She will replace Nicola Shaw, who left HS1 Ltd for National Grid earlier this year.
Prior to her role at Govia Thameslink, Crowther was director of operational services at Network Rail. She has also worked for Railtrack and British Rail.
“I am delighted to be taking on this role. High Speed 1 is the UK’s only high speed line which has transformed rail travel through Kent and into the continent,” said Crowther.
“Its growth and performance in the last nine years are testament to its success and I look forward to leading the business and helping continue this success for customers and passengers alike.”
HS1 Ltd chairman Rob Holden added: “As someone who joined the rail industry as a graduate, Dyan’s experience made her an extremely strong candidate.
“She has a strategic understanding of HS1 as a business and a vision to take it forward. We are looking forward to welcoming her here properly at the start of our 10th anniversary year.”
