When it comes to transportation infrastructure on land, there are two related branches: highway engineering, and railway engineering.  Highway engineers are constantly at work everywhere in the world to develop and implement new technology to deal with and improve our roadways.  This field demands knowledge of surveying and geology, materials and mechanical engineering, and civil engineering. Specifically, knowledge of new materials to build roadways from in order to reduce costs and increase lifespan is a priority for any highway engineer.  Engineers must consider traffic volume, types of vehicles, and other use cases in their designs.

Railway (or “railroad”) engineering is similar in many ways to highway engineering, as it also is essential for transportation in many countries (notably less so in the USA, though still vital.)  The science of railway engineering has been developed ever since the invention of the railroad and includes both track design and construction and train mechanics and structure. Today, an ever-growing emphasis on automation in train and track design reflects society’s need to cut costs and improve efficiency.  Accordingly, modern railway engineers must also master the subdisciplines of electrical, computer, and software engineering, in addition to the obvious mechanical and civil engineering problems involved.

This book covers the process of converting old designs to modern implementations.  A large number of illustrations and examples helps to provide better context for problems and make the science seem practical and accessible for new students.  The volume in question was written by Indian authors with the largest railway system in the world (India’s) in mind, and serves as an invaluable resource for international students who may be frustrated by American texts with outdated scientific units.
