From 2014, we'll be introducing 80 new trains. These will be air-conditioned and have walk-through carriages. To improve accessibility, they will also have wider doors and walkways, lower passenger alarms and a smaller gap between the train and platform.
The new trains will all be in service by 2016.
A signalling upgrade is underway on the District, Metropolitan, Circle and Hammersmith & City lines, which together make up 40 per cent of our network. This will allow us to run more trains, more often and more reliably. Combined with bigger trains that we can move more quickly and closer together, it'll mean more room - or capacity - on the lines.
When the upgrade is complete the combined line capacity will increase by 24 per cent, which means we can carry about 17,000 more passengers an hour.
Escalator replacement at Embankment
As part of Tube improvements, we are replacing four escalators at Embankment between Wednesday 8 January and early November 2014. As a result, there will be no interchange with the Bakerloo or Northern lines, which will not be stopping at the station in either direction.
Customers wishing to change trains at Embankment are advised to either:
Use alternative Tube routes by changing at a nearby station such as Westminster or Victoria.
Walk between Embankment and Charing Cross via Villiers Street - roughly a five minute walk. Oyster settings at both stations will be updated so customers are not overcharged, as long as they touch in and out in good time.
The escalators at Embankment were installed before the Second World War and have reached the end of their useful life. They will be replaced with new, custom-built machines which will ensure a reliable escalator service for many decades to come.
In February 2012, we completed major redevelopment work at Blackfriars station.
Benefits include an upgraded station with step-free access, increased capacity and better interchange between Tube and National Rail services.
