The Costain Skanska Joint Venture has broken through into the new Crossrail tunnels, as part of excavation work for the new Paddington station.
The JV contractor will now excavate the earth between the two tunnels. Once this completed, it will start building the station platforms and laying the track bed.
Costain Skanska JV construction manager Andy Mooney said: “Reaching the tunnels marks an important phase in the construction of Paddington station. The excavation down 16m underneath Eastbourne Terrace will allow us, once we have removed all of the 2,640 individual tunnel segments, to start the construction of the platforms and track bed.”
Tunnelling machines Phyllis and Ada built the new train tunnels through Paddington at the beginning of 2013 ahead of completing their 6.8km journeys to Farringdon in autumn 2013.
Following the completion of the platform and track bed construction, system-wide contractor ATC (Altsom, TSO & Costain) will commence fit-out of the new tunnels with track and other rail infrastructure.
The new Crossrail station is being constructed adjacent to the existing Paddington National Rail station under Eastbourne Terrace.
The 250m-long and 30m-wide station will include a 120m-long glass canopy.
