About Maglev Train
the National Science Museum provides people with an opportunity to experience state-of-the-art science technology. The museum contributes to improving awar eness of national science technology by offering them a chance to ride the Maglev train; an environmentally-friendly mode of transportation developed through government research and development. We invite you to take this opportunity to ride the only Maglev train in Korea, and experience future-oriented technology while running on a 995m track 8.8m above ground.
Travel Route
One-way trip between Science Center Station and Expo Station (Capacity: 44 seats)
Tickets
Tickets can only be purchased on-site the day of the ride. Lunch recess is from 12:00 to 13:00. Free tickets are distributed at the train station on a first-come-first-serve basis. A free ride is offered to those who hold admission tickets for the National Science Museum. (From 21 April 2008 to 31 September 2008) For those who take the train at the station in Expo Science Park, an admission fee for the National Science Museum will be charged. The admission will be determined in accordance with the admission standards of NSM.

History of Maglev Train in Korea
1988 – Started to develop and test an urban style Maglev
1993 – Operated Maglev train at Daejeon EXPO for exhibition purposes
1996 – Developed a bogie for UTM-01 vehicles through national research led by Ministry of Science and Technology
1997 – Completed a 1.1km test trak and developed UTM-01 vehicle
2005 – Developed UTO-02 vehicle through national research led by Ministry of Commerce, Industry and Energy
Features of Maglev Train
1. New transportation system which operates on the principle of levitation; vehicle hovers over track with no wheels. – The system has safe structure; the vehicle envelopes the track.It doesn’t create any friction besides that of the current collector.
2. Environmentally-friendly track transportation system – The system creates minimal vibration and noise that is 10 db lower than that of a wheeled-train. In terms of the number of electromagnetic waves produced, magnetic levitation technology produces only a fifth of what a television does and only a 10th of what a hair dryer produces.
3. Excellent driving performance – Maglev trains show smooth cornering ability and excellent uphill performance.
4. Inexpensive maintenance – Since Maglev trains have no wheels, costs for maintenance is automatically minimized.
Principles of Maglev train’s movement
1. “Maglev trains utilize the nature of magnets; attraction and repulsion.”
2. The train is levitated from the track by attraction/repulsion synergy created between electromagnets installed in the train and the steel rail.
3. Once the train is lifted from the track, a moving magnetic field created between the linear-induction motor coil and the conductor on the track propels the forward.
4. Maglev trains levitate on the principle of magnetic synergy. No engine. No rotating motor. The power of linear-induction motors alone.
Principles of Maglev train-levitation
When current flows between the vehicle magnets and track magnets, the train levitates. If the current between the magnets were not regulated, the possibly of the magnets attaching to one other would be high. But, a controller and a gap sensor simultaneously measure and maintain a 1 cm distance between the vehicle and the track.
Principles of Maglev propulsion
Maglev trains are propelled by a linear-induction motor; which shape is similar to a flattened rotating motor. The alternating current flowing through the coils of LIM (Linear Induction Motor) induce a moving magnetic field between the coils and the conductor installed in the track. The moving magnetic field created by the LIM induces vehicle propulsion.
Principles of Maglev propulsion
The operation of the Maglev train at the National Science Museum is temporarily on hold due to museum maintenance. Operation will resume once additional safety features are installed--and the system passes a comprehensive inspection and routine safety check.
