One particularly attractive boat journey is the 'backwaters' excursion in the vicinity of Kochi in Kerala. Several local tours are available. The Indian internal railway system is the largest in Asia and the second-largest in the world. Its trains carry over 12 million passengers every day. The network covers much of the country and is a quintessential part of the fabric of India, as well as being relatively inexpensive.
Express services link all the main cities and local services link most other parts of the country.
Buses connect with trains to serve parts of the country not on the rail network. Children 5-11 years of age pay half price, children under five travel free. Major trains carry restaurant cars. There is a special Indrail Pass consisting of a single non-transferable ticket which enables a visitor to travel on any train without restriction within the period of validity. It is sold only to foreign nationals and Indians residing abroad holding a valid passport, and replaces all other concessional tickets.
