Railway engineering is a multidisciplinary field in transportation engineering. It is concerned with the design, construction and operation of all types of rail transport systems. Railway engineering comprises mechanical design skills and knowledge of propulsion systems to design train vessels. Railway engineering includes civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering. Command, control and railway engineering, energy electrification, overhead contact system, light rail systems, on-track plant, train control systems, railway signalling and systems integration are some of the sub-fields of railway engineering. This book attempts to understand the multiple branches that fall under the discipline of railway engineering and how such concepts have practical applications. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. This book is a vital tool for all researching or studying railway engineering as it gives incredible insights into emerging trends and concepts.
