The wheel/rail interface is one of the most critical parts of an entire railway operation. Through a contact patch the size of a small coin, all the forces between the moving element (the train) and the static element (the track) are transmitted. These forces are immense, and if not properly…

Bombardier Transportation develops and produces bogies for a complete range of modern railway vehicles. The calculations and analyses of running dynamics play an indispensable part in the development of these products. This article outlines the usage of computer techniques to investigate vehicle dynamics during the individual product development phases of…

The bogies of railway vehicles have become a high-tech component nowadays. At Siemens, they are developed and manufactured for the whole company in a World Centre of Competence for bogies (CoC) in Graz/Austria, where the most modern technical methods are used in development and production. With totally new bogie concepts…

Conventional bogie designs suffer from a fundamental conflict of contradicting requirements: Either they are running stable at high speed, but are by no means track friendly when negotiating curves due to their stiff wheel set guidance, or they are able to smoothly follow curved tracks through radial orientation of the…

Siemens Transportation Systems (STS), formerly Simmering Graz Pauker (SGP), has almost 150 years experience in the railway business. The product range covered the development and manufacture of locomotives, freight and passenger cars – mainly for the Austrian Federal Railways (ÖBB). In the 1990’s SGP started the development of a high…

European freight wagon designers have for a long time been guided by the principle that wagons must be capable of being used on all standard-gauge railway networks in Europe. For more than 50 years the International Union of Railways (UIC) has standardised many freight wagon components – in particular their…
