This book is an important source of information on railway systems engineering. In railway applications, performance studies are important for increasing the durability of railway systems. One of the main objectives is to validate whether the working conditions are reliable and safe. This task not only requires analysis of the whole traction chain, but also needs authentication that the railway infrastructure is efficiently working. Therefore, many tests for detecting any dysfunctions on their proper operation have been developed. This book discusses the various basics of railway traction, providing suggestions on exploratory approaches to spot any dysfunctions as well as reliability and safety issues. This book aims to serve as a valuable reference for students, educators, scientists, faculty members, researchers, and engineers.
