These are the platform tunnels at Crossrail’s Bond Street station in December 2014. The 260-metre long platforms run parallel to and around 100 metres to the south of Oxford Street. Crossrail expects 220,000 passengers to use Bond Street’s London Underground and Crossrail station every day. The walls of these tunnels feature sprayed concrete rather than the ring segments used in the running line tunnels. CROSSRAIL.

Machinery works in the new platform tunnels for Liverpool Street station. Crossrail is building over 1.5 kilometres of platform and pedestrian tunnels. These tunnels are over 40 metres below ground level. CROSSRAIL.

Tunnelling machine Elizabeth sits at Whitechapel station. Crossrail used eight of these 150-metre long, thousand-tonne machines. In December 2014, with almost 90% of tunnelling complete, Elizabeth is one of just two machines still operational. The first machines started at Royal Oak, west of Paddington, in 2012 and drove eastwards to Farringdon. CROSSRAIL.

This is Farringdon. When it opens, it will be a very busy station with an estimated 90,000 daily passengers. The station will be an interchange with Thameslink (London’s north-south heavy rail link) and with London Underground. This could see 150,000 passengers using the interchange. CROSSRAIL.

These are some of the platform tunnels at Tottenham Court Road station. Alongside TfL’s upgrade of the existing Tube station, Crossrail is building a new station the length of three football pitches, four storeys below ground. Crossrail estimates that 200,000 passengers will use the new station when it opens.

The concrete segments identify this as a running tunnel for trains. It’s at Paddington and shows were the team building the station have broken into the running tunnel in order to complete the station. The station lies next to Paddington’s main line station which Brunel built. Crossrail is building it under Eastbourne Terrace and it will be 250 metres long and 30 metres wide. Crossrail expects daily passengers to reach 70,000. Services will run in open air from just west of Paddington to serve Reading and Heathrow Airport. CROSSRAIL.
