Vivek Express: Dibrugarh to Kanyakumari
The longest train route in India covers 4,286 kilometres and takes roughly 82 hours end to end. Most passengers board for a segment, not the full stretch, but those who ride the overnight portions through Odisha and Andhra Pradesh get something rare: a train moving through landscapes that shift from dense sal forest to red-laterite plateau to coast within a single night. The Vivek Express runs three times a week. Book a 3AC berth for the middle legs if you want the scenery without the full marathon.
