The Eurostar began service in 1994, whisking passengers from London through the Channel Tunnel (which runs beneath the English Channel) to Paris. Later track improvements cut the travel time between the two cities to just over two hours. Lines also connect London to Brussels, Belgium. The Eurostar trains are modified TGVs and travel at top speeds of 300 kph (186 mph). Some trains feature interiors by renowned designer Philippe Starck.
