The tunnel works through London.
The 8bn horizontal rail scheme has been completed.
Eight boring machines cut 26 miles on Earth (42km)of tunnels.
The service, which will begin on 2018, will run at Berkshire\'s reading and Essex\'s Shenfield.
While visiting the cross-rail site in fallingon, David Cameron said the project was \"an engineering victory \".
On Wednesday night, Victoria\'s breakthrough in Farringdon completed the tunnel crossing the capital.
The prime minister, London Mayor Boris Johnson and transportation minister Patrick McLoughlin went through the tunnel in Farringdon and looked closely at the tunnel machine.
Johnson said the completion was a \"historic day\" and marked a \"great success\" for the entire British economy \".
In May 15, 2009, the Canary Wharf in London\'s Docklands began to build cross-rail lines, and in May 2012 began to build tunnels.
During the peak period of construction machinery, tunnel construction of 100 is completed every week.
The fastest day to dig a hole was in April 16, 2014, when the boring machine completed 236ft (72m)

The horizontal rail tunnel consists of more than 200,000 concrete tunnel sections, each weighing 3 kilograms. 4 tonnes.
In order to establish a nature reserve, millions of tons of excavated materials were transported to the island of varassay in Essex.
Ten new cross-train stations are being built in central London, London\'s Docklands, and Abbey Wood in southern London.
The cross-rail is the largest construction project in Europe, with thousands of workers operating in dozens of locations.
It is estimated that the program will serve 40 stations and will generate at least 75,000 business opportunities.
The cross-rail project has completed 65% and engineers will now continue to upgrade existing stations and build new stations in central London and London\'s Docklands.
