Ballastless Track
for Urban Metros
Precision Metro Solutions
Urban metro systems demand high precision, uninterrupted service, and long-term structural integrity. Our ballastless track system for urban metros is based on precast plinths, offering a modular, high-performance solution for elevated and underground corridors.
Leading change in Indian Railways
At Patil Group, we pioneered the adoption of RHEDA ballastless track systems in India—an achievement that reshaped track infrastructure for one of the world's busiest rail networks. Our journey was marked by challenges, breakthroughs, and innovation, and it has set a new benchmark for safety, precision, and reliability in Indian Railways.
The challenge
- Convincing Indian Railways to adopt Patil RHEDA technology was not easy, as existing BLT designs were already in place.
- Existing BLT systems were failing, raising safety concerns for millions of daily passengers.
- Decision-makers required extensive assurances on design and safety before considering a new system.
Turning point
In December 2006, after months of discussions, technical presentations, and outreach, we earned the trust of Indian Railways and secured approval to adopt Patil RHEDA sleepers.
Design and development
- Creating a sleeper for India's most demanding track system required unmatched precision and innovation.
- We explored multiple design iterations before arriving at the final mold.
- Extensive R&D ensured every sleeper met exacting safety and quality standards.
- We tested different material combinations and tolerance levels to optimize performance.
Outcome
A sleeper design that delivers both strength and reliability, validated through repeated trials.
Installation and execution
- Execution demanded as much precision as design.
- Transporting and handling sleepers required specialized equipment such as spindle bars to prevent damage.
- Every step had to be finalized before concrete pouring, as changes were not possible afterward.
- Working under strict delivery timelines of just 40 days, we maintained rigorous monitoring to ensure zero errors.
Outcome
Safe, efficient, and timely installation of Patil RHEDA sleepers—demonstrating our ability to deliver complex infrastructure under pressure.
Legacy and impact
Today, Patil RHEDA and BLT systems are synonymous with reliability in Indian Railways. By overcoming early challenges, we proved that innovation and perseverance can redefine national infrastructure.
With reduced on-site casting, consistent alignment, and low maintenance needs, it supports fast-track construction and dependable daily operations across dense urban environments.
Ballastless Track System for Main Lines
In mainline applications—such as tunnels, bridges, and station zones—ballastless track offers a durable, low-maintenance alternative to conventional systems. Our design accommodates high-speed movement, continuous loading, and complex terrain.
This system has been successfully deployed in multiple metro projects, including:
- Bangalore Metro
- Delhi Metro
- Mumbai Metro
- Chennai Metro
Engineered for long operational life with minimal intervention, the system ensures stable geometry, reduced deflection, and consistent track performance under both freight and passenger traffic.
