Kolkata-based infrastructure builder GPT Infraprojects Limited secured a ₹103.58 crore railway contract after its wholly owned subsidiary emerged as the lowest bidder for a signalling modernization package under North Eastern Railway.
A regulatory filing submitted to stock exchanges on Tuesday, November 10, confirmed that the subsidiary, Alcon Builders and Engineers Private Limited, bagged the L1 position. The mandate demands extensive electronic interlocking over key rail routes in the Varanasi Division. The engineering blueprint requires design, programming, supply, installation, testing, and commissioning under RDSO specification RDSO/SPN/192/2019. It also encompasses indoor and outdoor signalling work, materials supply at Siwan Junction and CHPG Station, automatic block signalling along the CPR Junction–CI–CHPG section, and optical fibre cable deployment across the GKC-BTT and CPR Junction–CI–CHPG alignments.
Last month brought similar momentum. Alcon Builders clinched a ₹134.11 crore railway signalling contract, inclusive of GST, from the Chief Signal and Telecommunication Engineer of Western Railway’s Ratlam Division. That project encompassed survey, design, supply, testing, and commissioning of four-aspect automatic block signalling systems, dual multi-section digital axle counters at auto huts, and station-level interlocking alterations.
Combined, the two division mandates add roughly ₹237 crore in fresh signalling obligations to the company's order pipeline.
| Rail Division | Contract Value | Core Scope | Status |
|---|---|---|---|
| North Eastern Railway (Varanasi) | ₹103.58 Crore | Electronic Interlocking, OFC, Auto Block Signalling | Declared L1 Bidder |
| Western Railway (Ratlam) | ₹134.11 Crore | 4-Aspect Auto Block Signalling, Digital Axle Counters | Awarded (Oct) |
The market took the announcement in stride. Shares of GPT Infraprojects traded at ₹112.15, having slipped over 1% during Monday's trading session ahead of the disclosure. The counter has witnessed volatile swings in recent months—periodically touching circuit boundaries despite contract expansions. Year-to-date, the stock is up 2.33%.
Next comes formal contract execution. Alcon Builders must now finalize documentation and clear security deposit milestones before formal letters of acceptance trigger site mobilization across the Varanasi division.
