Train travelling is becoming faster and safer due to the advancement in technologies. New technologies are adopted to cope with the increasing demand in the transportation sector especially in rail transport owing to the problems, like congestion, pollution etc faced in road transport. In the current scenario of growing urbanisation and terrorism, a need is felt for an efficient mass transit system ensuring passenger safety. Countries like Japan, China have developed new technologies in rail transit systems, which have simplified the life of commuters. Indian Railways are also not behind in the race of using new technologies. Indian Railways have started metro rails in Kolkata, Delhi and have launched new metro rail projects in many other cities like Mumbai and Bangalore. Over the past few years, positive steps have been taken in creating a modern Mass Rapid transit System in India. Many new technologies have been used in the construction and management of metro rails. The book describes different technologies used by countries world-wide. It covers the experiences and prospects of rail transport in different parts of the world. It also gives and idea of the efforts put in by the Indian Railways in upgrading and modernising their technology and provides a glimpse of their future plans. Indian Railways have taken an encouraging step towards the development of an efficient, new technology based mass urban transit system. With increasing urbanisation and rising population in India, building an efficient mass transit system is a challenge for Indian Railways. Success of Indian Railways to achieve this objective would solve the transportation problems of our cities.
