Eurotunnel
Groupe Eurotunnel S.A. manages and operates the Channel Tunnel between Britain and France. The Company operates the car shuttle services and earns revenue on other trains (freight by DB Schenker and passenger services by Eurostar) passing through the tunnel. It is listed both on the London Stock Exchange and Euronext Paris.
The railway operation involves 50.5 kilometres (31.4 mi) of double track railway in the main tunnels, plus extensive surface-level terminal facilities at Folkestone in the UK and at Frethun in France; the Eurotunnel operation is entirely self-contained, with connections near the two terminals to the respective national railway networks. Signalling and electric traction supply at 25kV AC are also under Eurotunnel control.
Train operation consists of operating shuttle trains conveying cars and separate trains conveying heavy goods vehicles between the two terminals. Other trains passing through Eurotunnel infrastructure are operated by the respective owners.
