Prince William joined transport secretary Chris Grayling and Network Rail chief executive Mark Carne to reopen London Bridge station following its £1 billion five-year redevelopment.
The redevelopment of the UK’s fourth biggest railway station started in 2013, to increase space and provide easier connections to other rail services and the tube to handle projected passenger growth.
Updates to the 12,000sq m station include the creation of additional 'through platforms', enabling 30% more Thameslink trains to stop there; by the end of 2019, there will be up to 16 Thameslink services an hour in peak hours.
A new street-level concourse, the size of Wembley football pitch, opened in January 2018, allowing passengers to access all the platforms from one place and new entrances and exits provide easier routes to and from the station; the station is now more accessible with the lifts and escalator access to all platforms, and with a larger retail offering due to open this autumn.
Carne said: "This is a station that represents a transformation in passenger experience, a catalyst for economic growth and a world first in the use of digital railway technology demonstrating our vision of the future.
"I give my thanks to the great people and great teams behind this fantastic project, as well as to our customers for their patience and understanding during these major works."
"We've already surpassed one degree of global warming," said Kristen Buida, manager of the London Climate Change Partnership.
