ROUTE ELEMENTS FOR HIGH-SPEED RAILWAYS WITH ELECTROMAGNETIC LEVITATION

The route elements for high-speed railways with electromagnetic levitation (EMS) are described for ultimate speeds of 400 and 300 km/h and passenger and freight services on a common track, as based on the characteristics of contact-free running and traction. In addition to sinusoidal transition curves and ramps, standard radii of 4,400 m (2,500 mm) are important elements, the small size of which results from the 12 degrees superelevation possible with EMS vehicles. The maximum longitudinal gradient is 35%, the rounding out of the change in gradient is circular. Vertical and horizontal curves can coincide just as rounding out and transition curves. The aerodynamically necessary distance between track centres on the open line, the required tunnel cross-sections and the spaces to be kept free are stated. The most important standard cross- sections are the supports, the cutting and the tunnel, for which the dimensions are given. It is concluded that particularly because of the special characteristics of the contact-free EMS technique with the possible selection of the route elements such as radius of curvature, maximum longitudinal gradiend and supports, the average route investment costs can be less than for conventional high-speed railway routes. The article discusses the results of research and development projects which have been assisted by the West German government.
