When did the first passenger train go through the Channel Tunnel?
The channel tunnel is between Britain and France. It is more than 20 kilometres long. It was built by British and French engineers. They started on opposite sites and met in the middle under the sea. They used specially-designed tunnel boring machines (TBMs) to dig the tunnels through the rock under the seabed. TBMs are enormous machines for digging tunnels. The machines used to dig the main tunnels were about 8.5 metres in diameter and 250 metres long. Work started in 1987 and the teams met under the seabed in 1991. The first passenger train went through in 1994.
