Arka Defence & Locomotives Limited (formerly Source Industries (India) Limited) is a BSE-listed company focused on railway and defence technology, based in Hyderabad, with a 42-year operating history.

Railway Technologies: Train Collision Avoidance Systems (Kavach) and associated sub-systems; design-automation tools for signalling and rolling-stock engineering; yard management and yard safety systems; safety-critical systems engineering; high-speed rail technologies; and the application of artificial intelligence and machine learning to design, verification and validation in railway engineering.

Defence Technologies: Tactical systems and military applications, with a primary emphasis on indigenisation and homegrown defence technologies. Building on the promoter group’s prior work in target simulation and mortar systems engineering, the Company is exploring and packaging products for evaluation by the Indian Army.

Our business model combines proprietary technology and IP development, competitive project acquisition, engineering services to railway administrations and OEMs, solutions for recurring operational bottlenecks, and recurring revenue development through incremental research and design.

The Company’s ambition is to establish itself as an intellectual-property-driven technology enterprise in these two sectors, rather than operate solely as a project-execution contractor. It aims to be a preferred technology partner for solutions that address specific, recurring operational and engineering constraints within railway and defence programmes.
