Leveraging patented engineering innovations and proprietary technologies, Kathmandu Podway Transport & Infrastructure Solutions deliver high operational efficiency with minimal environmental footprint. These systems ensure unparalleled reliability and safety in the automated transportation of passengers and cargo, optimized for a wide range of applications and challenging environments.
Operating Principle
Transport and Infrastructure Solutions by Kathmandu Podway utilize advanced technology for constructing next-generation pre-stressed transport overpasses, with the string rail as the core component. This string rail consists of a steel or composite beam housing a core bundle of pre-stressed tensioned wires (strings) and is fitted with a rail head. Passenger and cargo electric vehicles on steel wheels—known as uPods—operate automatically along this rail at speeds up to 150 km/h, with potential future speeds reaching 500 km/h.
Steel Wheel
differences from railway wheel pair: independent suspension, cylinder-shaped wheel supporting surface, flat rail working surface 99.8% efficiency no slipping in the contact patch insignificant contact stress (about 200 Mpa) minor wheel rolling resistance symmetrical rail head wear
String Rail
absence of joints and temperature seams high track evenness comfort and smooth running high movement speed minimum material consumption
The string rail track structure replicates the hanging bridge combining all of its primary components
String Rail
The horizontal load on the overpass—approximately one thousand tons, which is two orders of magnitude lower than that of suspension bridges—is absorbed by anchoring structures positioned up to 10 kilometers apart. The supporting towers bear minimal vertical loads, allowing for a more lightweight design and reducing the need for frequent installation, unlike traditional elevated roads, railways, or monorail systems. This engineering approach enables the construction of unsupported spans of up to 3 kilometers, making it particularly advantageous for traversing water bodies, deep gorges, densely built-up areas, or corridors with existing energy and transportation infrastructure.
By integrating these features, Kathmandu Podway fully satisfies the demands of modern intercity passenger transport systems.

Podway is an innovative, elevated transport system based on string rail technology developed by Unitsky String Technologies (UST). It consists of automated, driverless pods that travel on specially designed suspended tracks above ground, offering a sustainable, safe, and efficient alternative to traditional urban and intercity transportation.
Unlike conventional systems, Podway:
Reduces land use and environmental impact
Minimizes traffic congestion
Operates with high energy efficiency
Is scalable for both low-density and high-capacity routes
The system is ideal for modern smart cities, tourism zones, mountainous regions, and areas where conventional transport faces infrastructure challenges.
