Railvolution - a blend of “Rail” and “Evolution”

​

With over three decades of trailblazing excellence, Deltron Equipment & Systems Pvt. Ltd. stands at the vanguard of India’s railway signalling renaissance. Born in Kolkata in the late 1980s, Deltron has evolved from a precision relay services firm into a nationally revered engineering house—powering critical rail corridors with cutting-edge, CENELEC SIL-4 compliant solutions. From the first wave of relay interlockings to today's fail-safe digital block interfaces and embedded safety logic, Deltron has partnered with Indian Railways through every era of modernisation. Our robust infrastructure—spanning 65,000+ sq. ft. of fully integrated manufacturing and R&D space—delivers end-to-end control over design, development, and deployment. With a product suite trusted at over 10,000 locations across India and overseas, our domain footprint is both broad and deep. We are more than a signalling company. We are enablers of safety, stewards of innovation, and trusted collaborators to global technology leaders. With ₹100+ crores in revenue and a clear investment vision aligned with ‘Make in India’, Deltron invites the railway stakeholders to partner in building a smarter, faster, and safer tomorrow—on steel rails and across generations.
