Indian GPT Infraprojects Subsidiary Emerges as Lowest Bidder for ₹1.036 Billion Northeast Railway Signaling Project

en.Wedoany.com Reported - On November 10, India's GPT Infraprojects disclosed to the stock exchange that its wholly-owned subsidiary Alcon Builders and Engineers has been identified by Northeast Railway as the lowest bidder (L1) for a signaling project valued at ₹1.0358 billion (approximately ₹1.036 billion). The project is being procured by the Office of the Chief Signal and Telecom Engineer of Northeast Railway, with the scope of work covering 18 stations in the Varanasi railway division, including automatic block signaling systems and optical fiber communication line works. The project is currently at the stage of lowest bidder confirmation.

The station signaling works involve 16 centralized control stations, as well as two distributed control stations at Siwan Junction and CHPG station. The scope includes design, programming, equipment supply, indoor and outdoor installation, testing, and commissioning of electronic interlocking systems, which must comply with the Research Designs and Standards Organisation (RDSO) technical specification RDSO/SPN/192/2019 and its latest amendments.

The electronic interlocking system will provide centralized control and safety verification of station signals, points, and train routes, ensuring that interlocking conditions are met between train routes. In addition to station equipment, the works also include automatic block signaling construction on the CPR Junction—CI—CHPG section, as well as optical fiber cable works on the GKC—BTT and CPR Junction—CI—CHPG sections.

Among these, the automatic block system is responsible for signaling control of train movements on the section, while the optical fiber lines carry signaling and communication data transmission. The three parts of the works are implemented in combination, covering station interlocking, section train operation control, and communication infrastructure.

GPT Infraprojects is participating in this project through its wholly-owned subsidiary Alcon Builders and Engineers. The company disclosed the lowest bidder result to the Indian stock exchange on November 10, 2026, and the subsequent purchaser confirmation and formal award procedures remain to be completed.
