People in India travel a lot especially during festivals, in weddings, on holy occasions and in holidays. The most eager traveler is the rural folks who are not privileged enough to go on holidays. The people of the country are tradition keepers hence change does not come fast.
India still travels in rail. The Indian Railway provides the most popular mode of transport to the people. Incidentally it is the cheapest as well as most networked system. No wonder Indian rail journeys are most written about. The journey can be very comfortable if you are traveling in air conditioned class with a reserved berth. But not many can afford it.
The largest number of travelers crowd the trains and buses during holy occasions like the Kumbh Mela. This is followed by those going in to attend a political rally. Seasonal travel during holidays - Diwali, Post Exam (summer), Holi, Marriages, create the worst kind of rush in the trains. The tickets are booked in advance and it is very difficult to step in the sleeper class.
Bus is another mode of cheap transport in the land - and worst. Most of the state run buses are ill equipped for luxury and comfort but then they are the cheapest. For luxury and comfort the answer is luxury bus services. They are costly but nevertheless preferred by upper class since travel by personal car is costlier.
Air Travel is unthinkable if you have less money or your company does not sanction. Most of the air travelers are Government employees, Employees of big companies and the jet set who have fat load of money. The middle class flies only in emergency or during pressing need for quick travel.
It is the only way. If you wish to experience the land from close train travel is the best followed by a bus or taxi. Taxi is very costly used only by corporate big wigs and tourists on holiday. For holiday makers from foreign countries taxi is most recommended. It is most comfortable to travel for short distances from one destination to another. Car Rentals and Motor Home rentals are available as well but it is not yet very popular in India.
