What Advanced Rail Controls does

Advanced Rail Controls Private Limited (ARC) was an RDSO-approved OEM that developed indigenous embedded control solutions for railway rolling stock. Founded in 2005 in Bangalore and ISO-9001:2015 certified, the company specialised in designing and manufacturing interoperable subsystems for three-phase electric locomotives (WAP5, WAP7, WAG9 classes) used by Indian Railways. Its core technology stack was built on IEC-61375 Train Communication Network architecture and IEC-61131-compliant control software, with proprietary products spanning Vehicle Control Units (VCU), Driver Display Units (DDU) in Linux and DOS variants, Distributed Power Wireless Control Systems (DPWCS), Brake Interface Units (BIU), Remote Monitoring Systems (RMS) with GPS and cloud telemetry, Hall-effect traction motor speed sensors, Doppler radar-based adhesion control systems, fire detection units, functionally equivalent PCB replacements for obsolete MICAS-S2 boards, and master controllers. ARC's portfolio also extended into full propulsion-system integration, including what is described as the world's first 3,100 HP hydrogen-fuelled locomotive propulsion system for retrofitting at NTPC's Sipat facility.

The company served a narrow customer base consisting of Indian Railways and government-linked entities such as NTPC, addressing pain points around legacy electronic obsolescence, safety and signalling compliance (including KAVACH/TCAS integration), operational efficiency, heavy-haul distributed power operation, and decarbonisation of diesel freight locomotives. Revenue was generated exclusively through B2B direct sales to government buyers via competitive tendering, with contracts structured as one-time supply, installation, and commissioning engagements typically executed over an 18-month timeline. ARC operated as a wholly-owned subsidiary of publicly traded Concord Control Systems Limited until 9 May 2026, when it was merged into the parent, transferring all assets, liabilities, and contracts. The parent's consolidated H1 FY26 revenue of Rs 81.55 crore (+63.92% YoY) and net profit of Rs 16.02 crore (+93.48% YoY) reflect the scale of operations absorbed through the merger, with ARC's order book having exceeded Rs 450 crore as of December 2025 across loco wireless control, hydrogen propulsion, and remote monitoring tenders.
