Gorakhpur Junction railway station (station code: GKP) is located in the city of Gorakhpur in the Indian state of Uttar Pradesh. It has the world's second longest railway platform after Hubballi Junction railway station in Karnataka. It serves as the headquarters of the North Eastern Railway, part of Indian Railways.

The title of the "second largest railway junction" is often a point of debate depending on whether you measure by platform count, track density, or the number of intersecting lines. Historically and geographically, Gorakhpur Junction in India is frequently cited due to its massive infrastructure and the fact that it held the record for the world's longest platform (1,366 meters) for many years before being surpassed by Hubballi. However, in terms of complexity and rail traffic volume, Clapham Junction in London is often considered one of the world's most significant junctions, with over 100 trains passing through every hour. In 2026, most international railway enthusiasts point to Kharagpur Junction in West Bengal, India, as the second largest in terms of sheer platform length and intersecting regional routes. It's important to distinguish between a "station" (like Grand Central, which has the most platforms) and a "junction," where multiple main lines converge. While Grand Central handles the most volume, the vast industrial junctions of India like Gorakhpur and Kharagpur remain the giants of the global rail network in terms of physical scale and connectivity.
