Type of course: Compulsory
Prerequisite: Nil
Rationale: Railway is important mode of surface transportation. Railways are economic for the long
distance transportation of passengers and freight on the land. India has the second largest Railway network
in the world. At present in the India, the share of goods transportation in railway is reduced than the
roadways. There is a very good scope of developing high speed trains and special corridors for freight transportation in India. Bridges and Tunnels are essential to provide safe and economic passage
over/through obstructions to railway or road corridor. The study of this subject provides necessary
knowledge of railway track, its component parts, geometric design, points and crossings, stations and yards, signaling and control system, maintenance, modern development and safety in railways. It also provides
knowledge of types of bridges, bridge super structure and sub structure, loads acting on bridges, bridge
hydrology, bridge maintenance, tunnel alignment, tunnel construction in different types of grounds, tunnel - ventilation, lining, safety and lighting.
