Transport for London has announced that 13 more underground stations are set to have step-free access by spring 2022.

It includes Sudbury Hill, which becomes the latest station in Harrow to secure the facilities after Harrow-on-the-Hill was given the go-ahead for 2019.

Campaigners have relentlessly called for the situation at a number of stations to be improved, as an increasing number of people struggle to use them safely and effectively.

This announcement comes as part of a £200 million investment, which seeks to provide the largest boost to step-free access in the Tube’s 155-year history.

Navin Shah, London Assembly Member for Harrow and Brent, said: “We have a fantastic transport network but we need to ensure it is accessible to everybody visiting, or living and working in, our city.

“It’s great to see that Sadiq Khan is taking real action to improve accessibility and that people in Harrow will directly benefit.

“This work will make our station much easier to use for people with disabilities, and parents using pushchairs.

“It's an important way of making our local area that much more inclusive, and reflects the Mayor's commitment to ensuring we are a city for all Londoners.”

He added that he will be pushing the Mayor further by reminding him that disability access goes beyond step-free and hopes to see measures taken for those with sight and hearing difficulties.

Mr Khan hopes to see 40 per cent of underground stations have step-free access by 2022, which will be an increase of 14 per cent from 2016.

He said: “It’s vital that we make our transport network accessible to all Londoners and visitors.

“These improvements are going to make a big difference in helping Londoners move around our city and show the real progress we are making to improve accessibility right across the capital.”

The issue of step-free access at stations around Harrow has struck a chord with the community, with a number of people getting behind petitions to ensure that changes are made.

While they have welcomed the decision at Sudbury Hill, following on from the announcement that Harrow-on-the-Hill will be kitted out by 2019, they believe there is much more that can be done.

Kuha Kumaran, who launched an appeal after witnessing many people struggle at South Harrow station, said: “This is a high-priority issue. We have a duty of care for the elderly and the most vulnerable people in our society.

“These people are responsible for the democratic freedoms we enjoy today but they themselves cannot experience life fully because they struggle with public transport.”

Councillors in Harrow have written to Mr Khan and Transport Secretary Chris Grayling to pledge their support for accessibility to be improved at Canons Park, Hatch End, Headstone Lane, Kenton and Northolt Park.

They also want improvements at North Harrow, Northwick Park, Queensbury, Rayners Lane, South Harrow, and West Harrow.

Leader of Harrow Council, Sachin Shah, said: “Improving accessibility at all train stations within the London Borough of Harrow and the train stations immediately on the Borough’s border would enable even more Harrow residents and visitors to Harrow to travel independently, making travelling easier for a large number of people, especially those who are older, disabled or travelling with children in pushchairs.”
