Increasing the utilization rate of regenerative braking energy in rail systems is one ongoing applications increasing significance recent years. In systems, made with two ways, mechanical and electrical. While released due to cannot be recovered, electrical can reused as energy. This varies according dynamics system it given back grid, stored storage devices or burned resistors (it not desired)...

Matching analysis is a key step in the process of verifying adaptation carbon-ceramic brake discs to high-speed trains’ braking system. Relevant research on matching tends be carried out only single parameter disc. Due this lack comprehensive analysis, data-driven, parametric method proposed address problem. We have summarised parameters three dimensions: assembly interface, physical characteri...

The observed difference in perceived annoyance caused by train and highway noise at the same averaged noise level, has led to the introduction of the ‘railway bonus’. This bonus has found its way to the noise legislation in many countries, leading to more relaxed restrictions on time averaged noise levels, LAeq. With the introduction of high-speed trains and train-like transportation systems ba...

Vibration Analysis of Rails Excited by High-Speed Trains. This was the topic of talks by Volker Mehrmann and Christian Mehl from the Technical University of Berlin. In collaboration with the company SFE they study the resonances when rail tracks are excited by high speed trains, the goal being to reduce noise and vibrations in the trains. The new ICE trains travel across Europe at speeds as hig...

The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc.). On the other hand, they are extremely expensive, mainly due to high installation and maintenance cost of the catenary system, including...
