New Army mono rail transforms supply lines at 16,000 ft in Arunachal

The Indian Army has deployed an indigenous high-altitude mono rail system at 16,000 feet in the Kameng Himalayas of Arunachal Pradesh, marking a significant advance in military logistics in one of the country’s toughest terrains.

A defence spokesperson said on Friday that the Gajraj Corps has operationalised the system to ensure uninterrupted supply to remote forward posts that are frequently cut off due to snow, steep gradients, unstable surfaces, and unpredictable weather.

The mono rail system, conceptualised and engineered in-house, has been designed to address long-standing challenges in high-altitude operations where traditional transport methods often fail. The equipment is fully validated and already functioning as a reliable logistics lifeline.

Capable of carrying more than 300 kg of load in a single run, the system enables the transport of ammunition, rations, fuel, engineering equipment, and other mission-essential stores. It is built to operate day or night, with or without escort, and remains functional in difficult conditions, including storms or hail.

Officials said the terrain in the Kameng Himalayas—marked by barren cliffs and extreme altitude—routinely disrupts supply lines for days during heavy snowfall. The new system is expected to significantly strengthen the sustainability of isolated posts and enhance operational readiness.

The Army also sees potential for using the mono rail for casualty evacuation in stretches where helicopter operations are limited and foot movement is slow and risky. In such situations, the system could provide a safer and faster evacuation option across hazardous terrain.

A defence spokesperson said the deployment reflects the ingenuity and adaptability of the Army’s Gajraj Corps in developing practical, mission-focused solutions for complex operational environments.
