Louise Cheeseman, Managing Director of Hull Trains, will move to TfL on 2 August as its new Director of Buses.
Cheeseman joins TfL at a crucial time to help lead a sustainable recovery from the pandemic and the de-carbonisation of the bus network.
Cheeseman said: “I am immensely proud to be joining TfL - an iconic organisation I have long admired.
“The opportunity to run the London bus network, the beating heart of the capital's transport system, is enormously exciting and I can't wait to get started.”
Gareth Powell, Managing Director of Surface Transport at TfL, added: “I'm thrilled that Louise will be joining us to lead the decarbonisation of London's buses while helping this iconic form of transport support London's sustainable recovery.
“Louise's proven track record of success in operations and people leadership stood out in a high-calibre field of candidates. I'm very much looking forward to working with Louise at such an important time for the city.”
