In a landmark achievement for national infrastructure, Rail Vikas Nigam Limited (RVNL) has commissioned India’s first-ever 3D printed railway building. Located at Parvatipuram Railway Station (Andhra Pradesh), this 1,076 sq. ft. Gangroom (Gangman Hut) was constructed to provide track maintenance crews with a modern, durable, and efficient base of operations.
Redefining Railway Infrastructure
This project, part of the Vizianagaram–Titlagarh third line initiative, demonstrates how additive manufacturing can fast-track the modernization of the Indian Railways network.
- Record-Breaking Speed: The entire 100-square-meter structure was completed in just 24 days, a fraction of the time required for traditional masonry.
- Complex Geometries: The design features signature wavy wall patterns and textured elevations that are difficult to achieve with conventional formwork, providing both aesthetic appeal and structural rigidity.
Functional Design for the Workforce
The Parvatipuram Gangroom is designed specifically for the utility and comfort of the railway’s “gangmen” (track maintainers). It includes:
- Dedicated Rest Zones: Comfortable spaces for staff during breaks.
- Secure Tool Storage: Integrated areas for heavy maintenance equipment.
- Modern Lighting & Ventilation: A layout optimized for natural light and airflow, tailored for the local climate of Andhra Pradesh.
Sustainable & Future-Ready
By adopting 3D concrete printing, RVNL has set a new standard for sustainable public infrastructure. The digital construction process significantly reduced material waste and minimized the environmental footprint of the site. This “proof of concept” paves the way for the rapid deployment of station buildings, ticket booths, and staff housing across the Indian Railways network.
