The UK Department for Transport (DfT) and Transport for London (TfL) have announced plans to make the remaining seven stations step-free on the Crossrail route.

Eight stations on the route are already step-free and work to upgrade or construct 25 more to give step-free access is currently underway.

The route will serve 40 stations from Reading and Maidenhead in the west and Shenfield and Abbey Wood in the east.

"Crossrail is going to transform how people travel in and across London and we are committed to making the entire railway open to everyone."

The stations to become step-free are Seven Kings, Maryland, Manor Park, Hanwell, Iver, Taplow and Langley.

UK Transport Minister Stephen Hammond said: "World-class transport networks are a vital part in the national economic plan but they have to be accessible to all. This is why everyone in the Crossrail family supports the aim of making all of the route accessible. The publication of this study is a step in the right direction."

TfL and the DfT are currently seeking funding options to pay for these improvements.

Crossrail will be fully operational by the end of 2019. It will operate a train fleet, which will be in compliance with the latest standards of accessibility.

Each carriage will provide both visual and audio information about the train’s journey.

Crossrail is expected to generate at least 75,000 business opportunities and 55,000 full-time jobs in the country.

London Underground and London Rail managing director Mike Brown said: "Crossrail is going to transform how people travel in and across London and we are committed to making the entire railway open to everyone."
