I realised long back that security & automation are the way forward and started to do my share in bringing latest technologies to India, specifically for the Indian Railways; so that their Signalling & Security Systems are enhanced, modernised & automated, to build a robust structure, which prevent train accidents, which cause widespread damage, loss & tragedy, from happeningI have been a great supporter of Make in India, and I was determined to get access to the latest signalling, communication & security technologies for the Indian Railways. Indigenous manufacturing using international technology transfers was the call of the day & it has been & will be my mission.I set up Sigma and Texmaco Transtek, with a focus to design, develop, manufacture & establish modern technology for Indian Railways. Based in Kolkata, West Bengal, India, over 50000+ sq ft, Sigma now provides complete indigenous solutions for Manufacturing, Engineering & Testing for the Signalling & Communications Division, Indian Railways.We work towards "AatmaNirbhar Bharat" by indigenising foreign technology & providing turnkey, timely, rail infrastructure development solutions at low cost; aiming at growth of rail transport and creating new jobs, thus boosting the overall economy.Our partners, Altpro from Croatia - a specialised company which provides safety, critical, signalling systems used on railway infrastructure & vehicles, had been vying for access to Indian Railways. They offer a wide range of train detection systems, level crossing protection & INDUSI-based automatic train protection (ATP – i60 and PZB90). They have certified products from independent international certification institutions for highest safety integrity levels (SIL 4).Today, we provide a variety of modern & latest signalling & safety systems for Indian Railways infrastructure.Our forte is installation and commissioning of MSDACs, along with a fail-safe data transmission device, a combination that serves for secure, reliable & fast information transfer between locations. We use our in-house, Kolkata production & fabrication factories for realising our supplies.We have established mutually-beneficial partnerships & are providing Indian Railways with the best in Security, Communication & Signalling Systems. Our new endeavours & partnerships are targeted to further enhance the safety of the lifeline of country ie. Indian Railways.We have had & will have a great role to play in the modernisation, growth & betterment of the Indian Railways Signalling & Telecommunication Systems, amongst other verticals.
