A train journey lasting more than three days can offer a different way to experience India's changing landscapes, languages and food traditions. The Vivek Express, which connects Dibrugarh in Assam with Kanyakumari in Tamil Nadu, is widely recognised as India's longest train service by route distance. Covering around 4,188 km in approximately 75 hours, the journey takes passengers from the tea-growing region of the Northeast to the country's southern tip. A traveller named Ganesh, who posts on Instagram as @runontrack, captured his experience of the long-distance journey in a video. His post, captioned “India’s Longest Train Journey, Dibrugarh to Kanyakumari”, offers a glimpse into a trip that crosses several states and passes through varied landscapes along the way.
