Tube Lines has promoted Lee Jones to Director of Operations, following his successes running London Underground's troublesome Northern line.
In his new post, Jones will be responsible for the continued improvement of the Jubilee, Northern and Piccadilly lines, which together carry 40% of all passengers on the London Underground.
His brief will be to ensure smooth installation of new signalling systems, reducing journey times and boosting passenger capacity.
"Having run the Northern line for the last four years, I know better than anyone about the challenges Tube Lines faces. I'm looking forward to building on the company's successes and working with our teams to improve passengers’ experiences, system reliability and journey times," he said.
Lee has 37 years of railway experience, working for British Rail and Amey, from where he is on long-term secondment to Tube Lines.
Terry Morgan, Chief Executive at Tube Lines to whom Lee will report, said:
"I am pleased to welcome Lee into my Executive team and see his appointment as recognition of his achievements at Tube Lines. He has improved performance on the Northern line, successfully renegotiated our fleet maintenance contract with Alstom and championed people development and innovation across the company."
Lee succeeds Steve Peat who is leaving Tube Lines to join BAA as managing director of all of its airports except Heathrow on 1 July.
