In a major leap for railway infrastructure in Northeast India, IRCON International Limited has completed the full electrification of the Rajdhani main route passing through the Lumding and Tinsukia divisions, marking a significant step toward faster, greener, and more efficient train operations in the region.
The final authorized inspection and full-speed trial on the Dibrugarh–Duliajan section spanning 62 route kilometers and 93 track kilometers; were successfully conducted on Monday. The trial was overseen by Principal Chief Electrical Engineer (PCEE) Sandeep Kumar, accompanied by Divisional Railway Manager (DRM) of Tinsukia, Parag Katre.
“This milestone represents a transformative moment for railway operations in the northeast,” said PCEE Sandeep Kumar. “With seamless electric traction now possible along the Rajdhani corridor, we’re eliminating delays caused by engine changes, reducing travel time, and increasing overall efficiency.”
Carried out under the ambitious RE PKG-6 Project, IRCON has electrified 480 Route KM and 624 Track KM in the region, enabling trains to run on uninterrupted 25kV electric traction. This modernization ensures that both passenger and freight trains can operate smoothly across the northeastern terrain, which has historically suffered from limited connectivity.
“The operational benefits are immense,” added DRM Parag Katre. “The absence of traction changes not only saves time but also enhances service reliability, connecting even the farthest parts of the region with major Indian cities.”
Besides operational gains, the move is a big win for environmental sustainability. Electric trains emit significantly less carbon compared to diesel locomotives, aligning with Indian Railways’ broader push toward greener transportation and long-term cost savings.
Officials confirmed that passengers and freight operators will experience immediate improvements in journey times, punctuality, and service dependability. The electrified route also paves the way for future high-speed rail expansion and enhanced freight movement in the Northeast.
