At times rail travel can be uncomfortable and frustrating, but it is also an integral part of the Indian travel experience. The Rajasthan Tourist Development Corporation run the Palace on Wheels, a luxury, refurbished, air-conditioned train that goes on weekly tours of Rajasthan, with accommodation on board. There are places such as Himalayan valleys where trains don't go, buses are more faster. There are many places where buses offer a parallel service to the trains. Government buses are supplemented by private operators on many routes.
Private buses tend to be faster, more expensive and more comfortable.
Bus travel is generally crowded, cramped, slow and uncomfortable. You can hire a car and driver very easily, and are available at cheap daily rates. Driving in India is not for beginners. You should have an international driving licence to drive in India. Cycle-rickshaws are the least expensive form of transport .
