A walk to Darbhanga Railway station tells part of the story. Vijay Mahto, 40, has just arrived home from Amritsar, where he works as farm worker. “I had to return for Chhath. But I can’t stay too long because rabi sowing will begin in a few days and I will have to go back. Or else someone else will take my job. But yaad aati hai ... (I miss my family),” he says, walking rapidly through the crush. The railway station is packed with people returning home from Punjab and Delhi. He is part of the migrant labour force, which leaves the region for want of employment every few months. Darbhanga got an airport about four years ago. In this festival season, a passenger who did not want to be named confessed ruefully that he paid ₹53,000 for a one-way ticket from Mumbai. The airport hosts three airlines that run flights from Delhi and Mumbai. But to go to Bengaluru or Hyderabad by air is a tall order. There are no direct flights to Jaipur, for instance, or Surat, considered employment hubs by locals.
