Electrical Modelling of a DC Railway System with Multiple Trains

Modelling and control design for an electro-pneumatic braking system in trains with multiple locomotives

This paper focuses on the modelling and control design for an electro-pneumatic braking system used in multi-locomotives in order to achieve accurately and steadily braking control of heavy haul trains. To deal with various time delays, a T-S fuzzy model based on satisfaction degree is proposed to simplify the cylinder model construction and a fuzzy clustering algorithm with forgetting factors ...

Spatial modelling of railway noise propagation

In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...

Modelling of a PLC-Based Railway TraÆ Control System

Vibration Generated by Underground Railway Trains

The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...

Routing Trains Through Railway Junctions: A New Set-Packing Approach

Arguably the most important decisions facing railway companies today concern the effective utilization of available resources. One such problem, the motivation for this paper, entails allocating the track capacity of a junction to a timetabled set of trains so as to ensure quality routings are obtained. Large junctions are highly interconnected networks of track where multiple railway lines mee...
