Most of the faces around have East Asian features. The Maha Parinirvan Express, as this train is named, targets a pilgrim market, which includes Japan, Korea, Thailand, and Sri Lanka, among other countries. On this trip, the middle-aged men wearing spotless white shirts and trousers and carrying identical blue bags with an orange stripe are from Thailand. A younger set of people, with formidable cameras, is Korean. Over the eight days and seven nights of the journey, we are all to be transported, by train when possible and by road if necessary, to the places where Buddha was born, achieved enlightenment, preached his first sermon, and died.
