Metropolitan line

Metropolitan Line Manager Angela Back
Metropolitan line trains are having to turn around at Moorgate this weekend because of work at Liverpool Street underground station.
It's being prepared for the eventual arrival of Crossrail, which will give you even more transport links there.
It's disruptive, we know, but all part of the plan to upgrade the Tube.
What's going on?
You may already have noticed changes to the Metropolitan line, where our upgrade involves trains, tracks and signalling.
New trains
The Metropolitan line trains have done good service but now they're 50 years old and need replacing. In 2010 we started introducing new trains on the line.
One of the first things you'll notice about them is that they're fully air-conditioned and have more spacious walk-through carriages.
To help you during your journey, the trains are fitted with visual displays and feature automated station announcements, and there's also the reassurance of CCTV.
We'll keep introducing more new trains throughout 2011 and 2012. Eventually there'll be 58 new trains on the line in all.
New signalling
Signalling ensures trains run safely, and the new, more modern systems also mean we can run more trains, faster and with fewer delays.
We know it's not something you see or take much notice of but, combined with our new trains, it'll make big a difference to your journeys. Because we'll have bigger trains that we can move more quickly and closer together, it'll mean more room - or capacity - on the line.
That's good news because as London keeps growing there'll be more people using the Tube. When the upgrade is complete the line capacity will increase by 27 per cent, which means we'll be able to carry about 9,500 more people an hour.
See what the new Metropolitan line trains look like.
Kings Cross St. Pancras
In 2010, we completed a massive redevelopment of King's Cross St. Pancras that quadrupled the size of this key station.
It already sees more passengers a year than Heathrow Airport, and by the time of the Olympic and Paralympic Games, more than 100,000 people will pass through the station at peak times every day.
King's Cross St. Pancras is now modern and spacious, has step-free access to all lines, and is less congested thanks to new ways to enter and exit the station.
When will the work be finished?
