King's Cross station gets a £550 million makeover

The new roof over King's Cross is made of white steel beams, in a tessellated pattern of triangles. In the centre of the dome, the covering turns to glass and light flows in.

Let's hope these engineers aren't afraid of heights! They're making last-minute checks to the new roof over King's Cross station in London, which has just had a £550 million makeover.

The original station building has also been cleaned up - it's in the middle here with its yellow bricks. The station is Grade-I listed, which means it is considered to be of historical importance. Any building work is very carefully considered to make sure it doesn't damage the original building or spoil the way it looks.

Workmen in fluorescent orange overalls are seen on the concourse, adding the finishing touches to the station.

King's Cross station is used by 45 million passengers a year. The new station means there's more room for everyone - and more room for shops and cafés.

The building work has used over 1,000 tonnes of steel, one million specially made bricks, five million metres of cabling and not forgetting the hard work of over 5,000 engineers!

This photo from above shows the new station entrance - the white semi-circle to the right of the platform buildings. The station is 160 years old, so it was due a facelift.

The station is lit up in bright colours for the big launch. The first passengers will catch their trains here on Monday 19 March.
