Crossrail has unveiled plans to create a permanent line-wide art exhibition across eight of its new central and east London stations.
Work on Crossrail has exposed a burial ground opened in Farringdon at the time of the Black Death.
More than a dozen skeletons thought to be victims of the Black Death have been unearthed in the City of London.
Crossrail's giant tunneling machine has now broken through into the Canary Wharf station box - the biggest milestone so far.
Both machines have been working round the clock to create a section of new tunnels beneath the River Lea towards the new Canary Wharf Crossrail station.
A milestone in a £14.8 billion rail scheme was reached today with the breakthrough of a 1,000-tonne tunnel boring machine.
Named Elizabeth, the machine broke through 90ft down at the new Canary Wharf station in London which is being created as part of the Crossrail project.
With its sister machine, Victoria, Elizabeth is creating more than five of the 26 miles of tunnelling beneath central London that are being dug for Crossrail.
The 73-mile long route runs from Maidenhead in Berkshire in the west, through London to Shenfield in Essex in the east.
Passing through 37 stations, Crossrail will be ready by 2018.
London clay, thought to be fifty million years old, has been turned into a piece of 21st century art.
Bird Nest, created by east London sculptor Frank Harris, was made using material dug up during the building of the new Crossrail tunnels.
The piece is exhibiting at the Slade Shows 2013 this week at the University College London.
The unveiling of the unique artwork comes as Crossrail launches its Artist in Residence programme, providing artists the opportunity to use Europe's largest construction project and its workers as their muses to inspire creative art.
To celebrate four years since the start of construction, behind-the-scenes photographs have been released by Crossrail.
To celebrate four years since work began, workers for Crossrail pose in one of the world's largest man-made caverns at Stepney Green. Trains will run through the cavern in 2018 between central and east London.
A public consultation is being launched over the proposed route for London's new rail link, Crossrail 2.
There's two routes to choose from - the Metro scheme and Regional scheme - which could half journey times for some commuters.
The Metro scheme would go from Wimbledon to Alexandra Palace, mostly underground, stopping at Clapham Junction, Victoria and Euston.
The Regional scheme would take in the same central Wimbledon to Alexandra Palace route, but would stretch south west of Wimbledon into Surbiton and Kingston.
The consultation will be opened by Boris Johnson at Wimbledon Station this morning and will run until August 2.
New time-lapse footage has been released showing the progress being made below the capital on Crossrail.
More than five and a half miles of underground tunnels have now been dug.
These pictures show the work that is being carried out at the sites of Finsbury Circus and the new Liverpool Street Station.
The first Crossrail trains are due to run in 2018.
Foreign train companies have emerged as the front-runners to operate Crossrail, London's new high-speed underground service. Three international rail firms are the only bidders so far to declare an interest in running the trains and stations.
They include the company behind the Paris Metro, RATP and the firm which runs Hong Kong's underground system, MTR. The German railway giant DB will also apply for the franchise.
The £15bn railway linking Berkshire with Essex and Kent is due to open in 2018. Potential operators have until the end of this month to sumit expressions of interest.
Crossrail’s lead tunnelling machine has arrived at the new Crossrail Bond Street station and has constructed her 2000th tunnel ring as she passes through the first metres of the station.
Tunnelling machine Phyllis has reached the south of the new Bond Street western ticket hall at Davies Street having completed 2 miles of new tunnels. Phyllis is one of eight tunnelling machines constructing a marathon-equivalent 26 miles of tunnels between Royal Oak and Woolwich.
The new Crossrail Bond Street station features two new ticket halls at Davies Street and Hanover Square. Around 220,000 passengers a day will pass through the new station.
Crossrail has excavated two of five levels forthe new western ticket hall and will reach tunnel level later this year. Overthe next two weeks, tunnelling machine Phyllis will travel 250 metres to theeastern ticket hall at Hanover Square and pass the halfway mark in her journey.
There, she will meet a specially made underground chamber where workers will be able to reach the face of the cutterhead for the first time since she began her tunnel journey, allowing maintenance work to take place.
Bringing up the rear is tunnelling machine Ada who will reach the new Bond Street station later in the spring. Both machines will reach Farringdon at the end of the year where they will finish their journey.
Collectively Phyllis and Ada have constructed over 3.7 miles of new rail tunnels.
Bond Street station will be a major central London interchange connecting with London Underground services on the Central and Jubilee lines.
Andy Mitchell, Crossrail Programme Director said:
"Phyllis’ arrival at Bond Street is a significant milestone for Crossrail and within the next few weeks she will mark the half way point in her tunnel journey.
"When completed Crossrail will provide essential new links and additional transport capacity with an extra 1.5 million people able to reach Oxford Street within 45 minutes.
"These transport improvements together with the new commercial space created above the station will help boost the West End’s position as a thriving cultural and retail destination.”
