This is the point where new Crossrail trains coming from Ealing will enter the tunnels under central London.

Work on the two tunnels began in summer 2012, excavated by Phylis and Ada, two of Crossrails 1,000 tonne boring machines. Phylis, named after Phylis Pearsall who created the London A-Z and Ada, named after Ada Lovelace, one of the earliest computer scientists, carved out more than three miles of tunnels stretching from Royal Oak in the west to Farringdon in the East.

Acton Main Line is the last above-ground station passengers will pass before heading underground at Royal Oak four minutes later just before reaching Paddington Station.

The £14.8 billion new line from Reading and Heathrow in the west to Shenfield and Abbey Wood in the east will enable people to get from Ealing Broadway to Bond Street 11 minutes quicker, and reduce their journey time to Carnary Wharf by 18 minutes.

The 200m long trains, which will carry up to 1,500 people will begin running along the new line in 2019. 

Matthew White, Surface Director at Crossrail, said: “These latest images show how much progress is being made on Europe’s biggest infrastructure project. Once complete, Crossrail will transform rail transport in and around the capital, increasing capacity by 10 per cent and bringing an extra 1.5 million people to within 45 minutes of central London.

“The benefits of Crossrail in Ealing and Hillingdon are already being felt. The better transport links that the new rail line will bring are already encouraging investment, unlocking development opportunities and supporting local jobs and businesses.”

*This story has been corrected as the last above ground station before heading into central London is Acton Main Line and not Acton Central as I said before. Sorry for the slip-up.
