Indian Railways is planning to upgrade older passenger trains with newer, energy-efficient and quieter 6,000-horsepower locomotives. The engines will operate in pairs in a push-pull configuration to improve acceleration and enable smoother, faster journeys.
Each train would use two locomotives, providing a combined 12,000 HP. On suitably upgraded routes, compatible conventional trains could operate at speeds of up to 160 kmph. The system is aimed at modernising locomotive-hauled trains while retaining conventional coaches.
The new locomotives will also eliminate the need for separate generator cars used to power coach lighting, fans and air-conditioning. This could free up space and improve passenger comfort while making train operations more energy efficient.
Unlike Vande Bharat trains, which use distributed traction equipment beneath the coaches, the proposed system will upgrade existing locomotive-hauled services. Indian Railways plans to procure the locomotives through supply and maintenance contracts with private or public-sector technology partners.
The move is expected to bring faster and more comfortable journeys to conventional passenger trains while giving Indian Railways a way to modernise its existing fleet without completely replacing traditional coaches.
