This is not easy, so it would probably be easier to build new. How different are these standards to those required for the rail tunnels in the alps? This subject has been covered to death on both uk.railway and misc.transport.rail.europe. In summary, services other than London - Ebbsfleed - Ashsford - Lille - Paris/Brussels are not practicable in the current situation for two main reasons: 1) All platforms at which the trains call must be secure zones, will the only entry to the platform through security. This has the effect that if you have more than a couple of trains a day, you need dedicated platforms. Useful destinations such as Antwerp, Amsterdam, Cologne, Birmingham, Leeds and Manchester have no spare platforms and no space to build new ones. This could be solved by dealing with security and Immigration on board the train between London and Ashford (outbound) or Lille and Calais (inbound), putting undesirables off the train at Callais/Ashford. 2) Trains through the tunnel must meet very stringent safety requirements. Probably the most awkward of these is the need to be able to didvide the train to use part of the train to remove passengers so that a disabled and dangerous half-set can be abandonned in the tunnel, and the passengers can be evacuated. Conventional TGVs are indivisible sets, and coupled sets have no access between the two halves. ICE3s suffer a similar problem for different technical reasons. To solve this would either require the safety regulations to be eased, to something closer to those in place in other long tunnels in Europe (eg the Severn tunnel, the various alpine tunnels &c.). Both of these problems can only be rectified by changing the treaty between the UK and France that allowed the tunnel to be built. While not impossible, it would take a great deal of time and effort to make it happen, and most discussion on these two newsgroups has come to the conclusion that it is highly desirable from a railway perspective, it is unlikely to happen any time soon.
