Routes: The Eurostar train zips you from downtown London through the "Chunnel" to downtown Paris (15+/day) or Brussels (10/day) in 2.5 hours, faster and easier than flying. Main train stations are London St. Pancras, Paris Nord, and Brussels Midi/Zuid. Some departures also stop at Ebbsfleet, Ashford, Calais, or Lille. London — Amsterdam by rail takes 5 - 6 hours between city centers, with connection to a local train (not Eurostar) in Brussels. To compare London — Amsterdam flights, see www.easyjet.com.

It would take a bullet train 20 minutes to cross the Channel.
