The 6318 / Himsagar Express, India's longest running train journey, takes us on a journey from the Indian Himalayas to the southern-most tip of India, spanning over 3720 kilometres. The train takes over 72 hours (often with delays) and halts at over 70 stations, crossing 9 states in the vast expanses of India. A wide diversity of locals travel on this train - students returning home to their hometowns, farmers going from village to village, families and sadhus of making pilgrimage and even people just going to work for the week. Buskers, beggars, snake charmers, chai and hot meal hawkers, toiletries peddlers and newspaper wallahs regularly punctuate the festive and pensive air as they hop on and off the moving train as it passes through the ever-changing countryside landscapes and 'smell-scapes'.
