The five-car diesel-electric trains were ordered through a contract signed on May 10 worth Rs 839m ($US 7.1m), and were originally manufactured at the Indian Railways Integral Coach Factory in Chennai.

The trains will now begin test running, although full services are not expected to begin until the relaxation of Covid-19-related border restrictions.

The Jaynagar - Kurtha line was converted from narrow gauge to 1676mm through the India-Nepal Development Partnership programme, with work completed in 2018. It forms the first stage of a Rs 8.8bn project to upgrade the 70km route between Jaynagar and Bardibas, which will enable direct links between India and the Nepalese interior. The project is divided into three sections, and also covers the 18km Phase 2 section from Kurtha to Bhangaha, and the 17km Phase 3 from Bhangaha to Bardibas.
