CALGAS MOBILITY PRIVATE LIMITED

What CALGAS MOBILITY PRIVATE LIMITED does

CALGAS MOBILITY PRIVATE LIMITED is a Kolkata-based, founder-owned industrial firm established in 2001 that manufactures and distributes electrical and electronic spare parts for Indian Railways' rolling stock and associated infrastructure. Its in-house manufactured portfolio spans resistors, AC/DC capacitors, sensors, valves, stainless steel and brass fittings, surge arresters, power semiconductors (IGBTs and thyristors), bellows and metallic pipes, transformer spares, and high-voltage cables — components that sit inside locomotives, coaches, and traction systems. The firm complements this manufacturing base with an authorized Value Added Distributor operation for complementary partner brands (TIBCON, AAC, GCO Valves, OBLUM, Sapna, and others), giving it a single-source catalog across roughly 550+ customers comprising Indian Railways production units (CLW, DLW, RCF, BLW, ICF, PCFM), zonal railways, metro rail projects, BHEL, and private rolling-stock OEMs. Manufacturing is supported by a facility in Howrah, West Bengal.

The firm's business model is B2B industrial component supply into a regulated procurement ecosystem. Revenue is generated through direct sales of proprietary manufactured components and pass-through distribution of partner-brand products, with wins effectively gated by Indian Railways' vendor qualification and product approval regime across multiple production units and zonal procurement offices. Day-to-day operations are run by a small core team of 8 employees under continued founder leadership — Bimal Kumar Dugar (CEO), Santosh Kumar Bothra (Partner), Pankaj Dugar (Marketing Head), and Sonan Sengupta (CTO) — with no external institutional capital raised. The combination of narrow headcount, 24-year operating history, broad customer count, and a hybrid manufacture-plus-distribution model suggests an asset-light, relationship-driven distribution operation that uses manufacturing selectively to capture higher-margin categories.
