The Indian international railway system is the largest in Asia and second largest in the world. Travel is relatively inexpensive.
Many express services link all the main cities, and a selection of timetables is given below.
Other trains, many of them leisurely local services, link most other parts of the country. Buses connect with trains to serve regions not on the rail network. There is a special Indrail Pass consisting of a single, convenient ticket which enables a tourist to travel on any train without restriction within the period of validity. It can be obtained in India or through some foreign travel agents. Payment is accepted only in foreign exchange.
