[Abstract]
First of all, the medium-low speed maglev transit system structure ensures that derailment and overturn will not occur during train running. The biggest difference of medium-low speed maglev transit with that of wheel-rail transit lies in the absence of wheels and yet uses electromagnetic force supporting train instead. The train and the rails (guideway beam track) system are an integrated structure, namely, the train embraces the guided-way track while running, that, in terms of systematic structure, eliminates the risk of train derailment and overturn in operation. Secondly, the reliability of supporting is increased exponentially. Thirdly, using real-time information technology to supervise and control the reliability of supporting. Fourthly, in the most adverse condition, assuming a sudden power interruption while a train’s standby power supply also at fault, the train will sit on its own on the 10 mm high rails, the friction force on the track will stop the train. Passengers will feel a slight shaking, and emergency stopping will make passengers feeling inertial forward-move. The reliability of medium-low speed maglev transit is ensured by modern information technology. Only with information technology, continuously supervise and control the reliability of train supporting is possible. Namely, the information technology supports the safety and reliability of medium-low speed maglev transit at a higher level.
