Prospects, current and future lines of research, conclusions

Obviously, for lack of space, a whole range of issues have been left undealt with, but they are of no less importance: maximum starting efforts and couplings, load capacity and inservice power, the influence of the vehicles' lateral and vertical dynamics, generation systems, energy transport and capture, pantographs and floaters, service automation and traction control, regenerative brakes and energy recovery systems, and a long etcetera.

As a final conclusion, the most current areas of progress in research, development and innovation and their future prospects are mainly directed towards achieving a railway that is better adapted to the new global needs of mobility, sustainability and respect for the environment:

a. More efficient systems for generating, transporting, capturing, transforming, utilising, regulating and recovering energy.

b. Traction control and service automation systems, regenerative braking and energy storage systems, reversible electrical supply sub-stations and rail traffic management.

c. Multidisciplinary optimisation of infrastructure and vehicle design.

d. The design implications of vehicles, infrastructures and systems in energy consumption and the environmental impact of transport.

e. Optimisation of vehicles and infrastructures for their use in multimodal systems.

f. Calculation systems, predicting and optimising energy consumption and emissions.

g. Foreseeable consequences of technological development on the innovation of vehicles and infrastructures for sustainable mobility.

In railway applications, performance studies are fundamental to increase the lifetime of railway systems. One of their main goals is verifying whether their working conditions are reliable and safety. This task not only takes into account the analysis of the whole traction chain, but also requires ensuring that the railway infrastructure is properly working. Therefore, several tests for detecting any dysfunctions on their proper operation have been developed. This book covers this topic, introducing the reader to railway traction fundamentals, providing some ideas on safety and reliability issues, and experimental approaches to detect any of these dysfunctions. The objective of the book is to serve as a valuable reference for students, educators, scientists, faculty members, researchers, and engineers.
