Onboard the 15617 Guwahati - Dullabcherra Express, a train that connects the Capital city of Assam to one of the remote small towns in the state. Led by Siliguri (Ex-Kalyan) WDP-4D #40346, this journey showcases the changing landscapes of Assam. From the busy urban stretch around Guwahati to the calm greenery and hills that lead towards Dullabcherra.

The stretch from New Haflong to Badarpur Junction is often regarded as one of the most scenic railway routes in Northeast India, and for good reason. This section lies on the historic Lumding - Badarpur Hill Line, a route that winds through the heart of the Barail mountain range and showcases a blend of nature, engineering, and history. As the train leaves New Haflong, you immediately enter a landscape dominated by deep valleys, rolling hills, and dense forests. The tracks gently descend from the Haflong plateau, offering sweeping views of the lush green hill slopes on all sides. One of the highlights here is the run through the Jatinga Valley, famous for its magical fog and scenic visuals. Early mornings are especially stunning as the train glides through clouds and hills. Badarpur Jn acts as the gateway to southern Assam, linking the hills to the culturally rich and vibrant Barak Valley.
