Gorakhpur–Thiruvananthapuram North Raptisagar Express

The 12511/12512 Thiruvananthapuram–Gorakhpur Raptisagar Express is a long-distance Superfast Express train operated by the North Eastern Railway zone of Indian Railways. It runs between Thiruvananthapuram Central, serving the city of Thiruvananthapuram in Kerala, and Gorakhpur Junction, serving Gorakhpur in Uttar Pradesh via Chennai, Tamil Nadu. .^[1][2]

The Raptisagar Express refers to a set of long-distance express trains operating between southern and northern India. At present, these services run on a tri-weekly or weekly basis between Kochuveli / Ernakulam Junction in Kerala and Gorakhpur/Barauni in northern India.

The service was originally inaugurated as Train Nos. 5011/5012, operating between Gorakhpur and Cochin Harbour Terminus, running four days a week under the name Raptisagar Express. Alongside this, a bi-weekly service was introduced between Gorakhpur and Hyderabad as Train Nos. 5089/5090, later renumbered as 12589/12590 Secunderabad–Gorakhpur Express.

Subsequently, one weekly run of 5011/5012 was extended from Gorakhpur to Barauni, operating as Train Nos. 5221/5222, which later became 12521/12522 Ernakulam–Barauni–Ernakulam Raptisagar Express. Similarly, one weekly run of 5089/5090 was extended to Bengaluru (Yesvantpur) as Train Nos. 5091/5092, now operating as 12591/12592 Yesvantpur–Gorakhpur–Yesvantpur Express.

In the early 2000s, following the upgradation of these services to Superfast Express status, the train numbers were revised, and Train Nos. 12511/12512 were further extended to Thiruvananthapuram (Kochuveli).
