Indian Railways is one of the largest rail networks in the world and the best and most economical way to travel long distances in India. And like most public transport it is an excellent way to converse with local people and see the diverse landscapes of the country.
I have fond memories of standing by the open doors and watching the endless mustard fields whiz by in north India. Dozing off in the sleeper cars you’ll often wake up to the sounds of vendors on the platforms touting their goods during the short intervals the train stops. Chai, chai (tea, tea).
