China
Shanghai's Maglev airport train shoots you across 30km at over 500 kph - the world's fastest. Take it for an experience rather than ease, unfortunately it doesn't take you right into the city centre but the station is well connected by taxis which wait around the station.
A one-way ticket is just around GBP5 so well worth the experience.
Get a cab out to the Maglev stop and get the train to the airport - its the fastest train in the world and though the station is in the middle of nowhere, the experience is one you'll remember forever.
