A: Hi Joe! How was your trip to China?
B: Absolutely brilliant. I had a wonderful time.
A: In what way?
B: As you can imagine, I was on the move over the Chinese New Year in 2008 and managed to get around quite a bit.
A: Did you get to Shanghai?
B: Yea and while I was there I travelled on the new Maglev train.
A: Oh yeah! I've heard about that new magnetic train in China. What was it like?
B: It was like no other kind of train on tracks. In fact it was a flight.
A: A flight? How do you mean?
B: We lifted off early in the morning of the Year of the Horse and landed at the airport eight minutes later. But we never left the ground!
A: A flight in a train. Wow! That sounds amazing!
B: Yes, my flight was aboard Shanghai's brand-new Maglev (magnetic levitation) train, the world's fastest, most futuristic passenger line.
A: The train runs from the city centre to Pudong airport across the river from Shanghai.
B: Pu''.. what airport?
A: Pudong. P-U-D-O-N-G.
B: So what else is special about this flying train?
A: Well, the train rockets to 300 kilometres per hour in two minutes flat. Overhead, like a giant scoreboard, an LED blinks out our record-breaking progress till we top 430 kph.
B: That's faster than our local train!
A: Actually, the Maglev is faster than any speeding locomotive precisely because it's as much like a plane as any railroad we've known.
B: But why do you say it was a flight? Surely the train didn't have any wings?
A: No, nor wheels or engine either!
B: So, how does it work?
A: With magnets. First, powerful magnets lift the entire train about 10 millimetres above the special track, called a guide way. This directs the passage of the train. Other magnets provide the drive and braking, and the speeds - up to 500 km/h in test runs.
B: Is there a need for such speed?
A: Certainly not on such a short sprint, barely 30 kilometres from the subway in Pudong to the airport.
B: And where might this new train take us?
A: Athens to Thessaloniki in a flash at hyper speeds.
B: What are the disadvantages?
A: None yet! The Maglev is pollution-free, with no exhaust and almost no noise so I can't see anything wrong in that.
