Delhi: Indian Railways has approved a significant infrastructure project worth ₹398.36 crore to strengthen its digital communication and signalling network in the Western Railway zone. The project focuses on provisioning a state‑of‑the‑art 4×48 Optical Fibre Cable (OFC) backbone across the Ahmedabad and Ratlam Divisions, aimed at enhancing capacity, reliability, and operational efficiency.
The initiative forms a critical part of the broader “Provision of Kavach with communication backbone of Long Term Evolution (LTE) on balance routes of Indian Railways (Umbrella Work 2024–25)” scheme, which has been sanctioned at a total estimated cost of ₹27,693 crore under the Works Programme 2024–25 (PH‑33). Within this, a dedicated sub‑umbrella project for Western Railway has been approved with a budget of ₹2,800 crore, under which the present OFC deployment project has been sanctioned.
Extensive Optical Fibre Rollout Across 1,929 RKm
Under the approved plan, Indian Railways will lay optical fibre cables over 1,929 Route Kilometres (RKm) across the two divisions:
- Ahmedabad Division: 1,456 RKm of OFC network
- Ratlam Division: 473 RKm of OFC network
The deployment consists of 2×48 fibre optical cables, designed to strengthen the backbone communication infrastructure along key railway routes.
Supporting Advanced Signalling & Kavach Implementation
This ambitious optical fibre expansion is not just an infrastructure upgrade — it is a foundational requirement to support modern railway signalling systems, including the Kavach automatic train protection system.
By facilitating high‑speed, high‑capacity data transmission across the network, the enhanced OFC backbone will:
- Improve communication reliability between control centres and on‑ground signalling equipment
- Enable real‑time transmission of critical operational data
- Support safety‑critical digital systems like Kavach
- Enhance dispatching and train movement efficiency
These improvements are expected to significantly modernise day‑to‑day railway operations and safety protocols.
Step Forward in Digital Transformation & Passenger Safety
The sanctioned project marks a major step in the digital transformation of Indian Railways, aligning with the national objective of modern infrastructure and improved safety standards. With optical fibre networks serving as the backbone for data communication, Indian Railways aims to ensure seamless connectivity across remote and high‑traffic routes alike.
This investment is expected to improve operational efficiency, elevate service quality for passengers and freight customers, and strengthen the overall safety framework of Western Railway operations.
Project Impact & Future Outlook
Once completed, the OFC backbone will not only facilitate advanced signalling but also pave the way for future digital services such as:
- Real‑time passenger information systems
- Faster internet connectivity on trains and stations
- Enhanced surveillance and monitoring systems
- Support for next‑generation railway communication standards
The project underscores Indian Railways’ commitment to leveraging technology for safer, smarter, and more efficient rail networks nationwide.
