Abstract
High speed multiple-unit trains will be the perfect solution for passenger transportation in many countries. The conditions for this type of train are discussed and compared with other types of high speed transportation systems. Computers have made it possible to perform theoretical studies and simulations of the running of railway vehicles on a track with irregularities. Bogie design with different types of primary suspension and wheel profile are important parameters for good running characteristics and low maintenance costs. By tilting the car body it is possible to increase the speed through a curve approximately 40% with comfort preserved for the passengers. An accelerometer in the leading bogie is used to give a signal for required tilting angle. Passenger service with high-speed trains demands high power transmission through lightly-loaded axles to minimise track stresses.
