Gajraj Corps’ mono rail transforms high-altitude logistics

Capable of carrying 300 kg in one run, the mono rail marks a major leap in high-altitude logistics

The Indian Army’s Gajraj Corps has operationalised a first-of-its-kind indigenous mono rail system at an altitude of 16,000 feet in the Kameng Himalayas of Arunachal Pradesh, marking a significant breakthrough in high-altitude logistics.

According to Defence spokesperson Lt Col Mahendra Rawat, the system has been fully conceptualised, engineered, and deployed by the Army to solve one of the most persistent operational challenges faced by troops—maintaining supply lines to posts that remain cut off for long periods due to snow, harsh terrain, and unpredictable weather.

A game changer for remote forward posts

Operating in the harsh and barren expanse of the Kameng Himalayas, where cliffs, steep gradients, and high-altitude conditions frequently sever lines of communication, the Army needed an innovative solution to sustain year-round operations.

The mono rail system, capable of carrying over 300 kg of load in a single run, provides a dependable supply route to remote forward posts where no other mode of transportation is possible.

Lt Col Rawat said the system ensures seamless movement of vital supplies including ammunition, fuel, rations, engineering tools, and other mission-critical stores across gradients where traditional methods, including mule trains and manual carriage, often fail.

All-weather, round-the-clock capability

The system functions day and night, with or without escort, and remains operational in snow, hail, storm, or low visibility—making it a robust asset for one of the most challenging sectors along the northern frontier.

Potential for life-saving evacuations

Beyond logistical support, the mono rail has demonstrated promising capability for rapid casualty evacuation, offering a safe alternative in areas where helicopter evacuation is impossible and foot evacuation is slow and risky.

A reflection of Army innovation

Lt Col Rawat described the project as a testament to the ingenuity and adaptability of the Gajraj Corps. The in-house innovation enhances operational readiness and strengthens sustainability at isolated posts, demonstrating the Army’s commitment to developing practical, mission-oriented solutions tailored to India’s toughest terrains.
