The Rail mode of transportation is the cheapest and fastest mode of transport when it is compared with other modes of transportation.It is also called as mass transportation system. Railroad engineering is an interdisciplinary engineering field dedicated to building better, faster, more efficient rail systems. The railroad industry uses these special engineers to care for and plan railway systems that can transport goods and people. The discipline combines a number of engineering disciplines—electrical engineering, mechanical engineering, industrial engineering, and even computer engineering. They plan and deploy rail projects with specialized knowledge and help the transportation engineering world expand and maintain what's already built. Train control is part of a larger field of transportation engineering. The infrastructure of travel and transportation is a large part of creating a logical and practical civil infrastructure. Railway Engineering is a specialist domain in Transportation and Civil Engineering. Railway Engineering is a multi-specialty engineering discipline within the transportation sector and Civil Engineering. It is a specialist field with numerous functions or specialist areas which can be very specific and specialized or broad. However, the railway sector in one of the incredibly complex and challenging environments brings extremely rewarding fields along with it, which can bring the highest credibility. Railways are incredibly complicated and expensive systems that are exclusively designed for the efficient passage of trains to transport people, cargo, and equipment. The incredibly advanced trains which use rail networks are expensive vehicles, and so a Railway Engineer is all the time faced with different challenges. Railway Engineering is a branch of civil engineering in a broader sense. It deals with the construction, location, and maintenance of railways. Depending on the roles assigned within the Railway Engineering branch, an Engineer is supposed to be involved in the designing, maintaining, construction, and indulging in various operations of trains and rail systems that include monitoring and controlling the trains and the rail networks. Railway engineers can be found involved with the designing, construction procedure, maintenance works, operation of trains, and the train systems and also associated in the infrastructure that is must for railways, within the private sector or public sector. Railway engineers can be mechanical, electrical, civil engineers (structural or bridge), rolling stock engineers, plan engineers, architecture, specialist executives, and interfacing engineers. Each discipline has diverse different sectors and specializations. Railway Engineers hold mechanical design skills and knowledge of propulsion systems that allow them to design train vessels. Railway Engineers mostly found on-site supervising the rail system or performing any functions of the field.
