•Shanghai's Transrapid uses one set of electromagnets for suspension and the field for LSM propulsion, a separate steel rail on the guideway, and coils on the vehicles to provide guidance.
•Japan HSST uses one set of electromagnets for suspension and guidance and another set for Linear Induction Motor propulsion. The use of permanent magnets in Maglet allows doubling the magnetic gap and more than an order of magnitude reduction in onboard power requirements for suspension. The use of only one set of magnets means there is only one magnetic gap to control so guide ways, vehicle weight, and cost are lower.The use of small vehicles operating with short headway has many advantages such as operational flexibility and lighter guideway girders because there is only one vehicle on a girder and the spacing between vehicles ensures that beam oscillations produced by one vehicle do not impact the following vehicle.
