Collectively the stations service more than 15.5 million journeys each year but can pose issues for passengers with mobility restrictions.
Now, thanks to a £200m investment by the Mayor and Transport for London, they’ll gain step-free access, allowing more passengers to hop on and off at the station of their choice.
Work will begin at Buckhurst Hill later this year with work on the other stations starting next year.
Mayor Khan said: “I’m delighted that I can today announce that we will be bringing step-free access to these stations.
“It’s absolutely vital that we make our transport network accessible to all, and by investing more in step-free access than ever before, we’re doing what we can to help people right across the Capital.”
Mark Wild, London Underground’s Managing Director, added: “Improving accessibility across London to enable all Londoners and visitors to the city to travel spontaneously and independently is one of our top priorities.
“We have made good progress but we’re determined to accelerate the pace so that this vision becomes a reality for the millions of people who use our network every day.”
