Dynamics of railway freight vehicles

On the dynamics of European two–axle railway freight wagons

The design of European two–axle freight wagons can be traced back to the 1890’es. It has been and still is widely used in Europe because it is simple, rugged and cheap in price and maintenance. The internationally approved suspension for two–axle freight wagons in Europe is known as the UIC standard suspension (see Fig. 1). Each wagon has four of these suspensions. They consist of a leaf spring...

Scheduling railway freight cars

It is dif®cult to allocate the freight cars and to determine how to load the several varieties of goods into them. In order to improve ef®ciency, a knowledge-based system (KBS) is developed and integrated into the existing railway information system. This paper introduces the development of the system and the framework in which the KBS are integrated into the existing system environments. Under...

Control for Railway Vehicles

Structural Crashworthiness of Railway Vehicles

As a form of transport, rail has always maintained lower accident levels than its counterparts, the car and the airplane. The railway industry, however strives for still better safety measures to be implemented – a fact which intensifies with each accident that occurs. In the last years the continuous developments in technology, computer modeling capabilities and know-how have opened up various...

Comparison of the Economic Profitability of a Conventional Freight-Dedicated Railway Corridor and a Heavy Load Freight Corridor

By using mathematical models, this paper will compare the economic profitability of a heavy load freight corridor (30 t per axle) with a conventional freight-dedicated railway corridor (22.5 t per axle). This comparison concerns the construction and operation of a new, single-track of normal gauge, exclusively for freight traffic, and takes into account various demand values of freight volume (...
