These passengers are going to a religious festival. British colonial administrators in shorts and pith helmets can be seen marshalling the crowd. Indian trains were and still are often very crowded, with some passengers sitting on the roof or hanging onto the outside. Some people preferred to sit on the roof as it was much cooler than being inside the hot carriage.
