Summary
Bharat Heavy Electricals Ltd (BHEL) has received a ₹22.87 crore order from Indian Railways’ South Western Railway (SWR) to design, supply, install, trial and commission the indigenous KAVACH (Train Collision Avoidance System) across on-board locomotives and trackside locations. The equipment will be manufactured at BHEL’s Bengaluru facility, and the completion timeline is 18 months from the Letter of Intent issued on September 11, 2025.
KAVACH in One Minute: Why It Matters
KAVACH is India’s indigenous Automatic Train Protection (ATP) solution. It helps prevent signal passed at danger (SPAD), enforces speed restrictions, and aids collision avoidance by creating a continuous digital awareness between trains, signals and trackside equipment. With large-scale rollouts planned across Railways, each new contract both improves network safety and expands the vendor ecosystem—from software and electronics to wayside equipment and integration services.
SWR’s geography—including the Bengaluru division—is one of the busiest passenger and freight corridors in the south. A new KAVACH package therefore offers high safety leverage per rupee, and becomes a useful signal for investors watching rail-tech capital expenditure themes. (For context, other Rail PSUs have also been winning KAVACH work packages in 2025, indicating steady traction.)
The BHEL–SWR KAVACH Order: Key Facts at a Glance
- Order value: ₹22.87 crore (regulatory disclosure & media reports).
- Client: Indian Railways — South Western Railway (SWR).
- Scope: On-board KAVACH for locomotives + trackside KAVACH for stations, level crossings, interlocking cabins and automatic block signalling locations.
- Manufacturing hub: BHEL Bengaluru.
- Timeline: 18 months from LoI (dated 11 Sept 2025).
Investor takeaway: The ticket size is modest versus mega EPC or energy projects, but it’s strategic: rail safety tech carries repeatability and visibility as corridors are progressively equipped.
Why This Contract Is a Green Flag for Rail Safety (and a Signal for Investors)
- Safety Multiplier per Corridor
Deployments on busy divisions build demonstration effects—improving reliability, enforcing speed discipline, and reducing human-error risk. Expanding KAVACH creates follow-on opportunities for maintenance, upgrades and add-on kilometers. - Make-in-India Depth
The Bengaluru manufacturing base for KAVACH gear highlights domestic design and localization—good for supply-chain resilience and jobs, and attractive for investors tracking indigenization themes. - Pipeline Signalling
The Indian Railways KAVACH roadmap continues to widen with multiple award announcements across zones in 2025—supporting a multi-year safety capex cycle that adjacent vendors can participate in.
Deep Dive: What Exactly Will Be Installed?
On-board units inside locomotives talk to trackside equipment via radio and balises. The combined system:
- Monitors signal aspects & speed limits and enforces braking if needed
- Facilitates train-to-train and train-to-track awareness
- Supports automatic whitelisting of authorised movements during failures
- Integrates with station interlocking to maintain safe separation
SWR’s scope explicitly spans stations, level crossings, intermediate block (IB) sections and automatic block signalling (ABS) locations—the highest-impact nodes for risk reduction.
Timeline: 18 Months—What Happens When?
Months 0–3: Design Finalization & Lab Validation
System design baselined, BoMs locked, lab tests and interface matrices aligned to SWR requirements.
Months 3–9: Manufacturing & Pre-installation
Bengaluru shopfloors produce on-board racks, radios, balises, and wayside gear; factory acceptance tests (FATs) staged.
Months 9–14: Field Installation
Sequenced block-wise installs on locomotives & trackside, night blocks where needed; integration with interlockings.
Months 14–18: Trials, Commissioning & Training
On-track trials, safety case documentation, driver & signal staff training, and handover.
Risks & Mitigations (Investor Lens)
- Interface Complexity: KAVACH must talk smoothly to legacy interlockings—mitigated by pilot sections and staged commissioning.
- Supply Timing: Electronics lead times can stretch; domestic manufacturing reduces import friction.
- Operational Windows: Rail blocks are limited; program managers rely on night possessions and precise work packs to hold the 18-month date.
How This News Connects to Our Unlisted Shares Marketplace
While BHEL is a listed PSU, the rail safety digitization underway benefits a wider supplier universe, including unlisted component makers, contract manufacturers, software integrators, PCB assemblers, RF/antenna shops, enclosure fabricators, and field-services firms. Many of these operate pre-IPO or as private subsidiaries supplying larger primes.

Strategic Context: Rail Safety Is a Multi-Year Theme
- Breadth of Awards: 2025 has seen multiple KAVACH contracts across zones (e.g., SWR, ECR) via different PSUs/EPCs—evidence that execution is compounding, not episodic.
- Tech Stack Matures: Each project improves interoperability, expands approved vendor lists, and deepens local component ecosystems—exactly where many unlisted SMEs play.
- Policy Pull: Safety capex typically faces low political friction. Once corridors standardize on ATP, retrofits & maintenance become annuity-like flows for qualified vendors.
How to Read This as an Investor (Checklist)
- Follow the Milestones: LoI → PO → FAT → SAT → Provisional Acceptance → Final Acceptance. Value often accrues earlier for component suppliers.
- Watch Bengaluru Clusters: The order emphasizes Bengaluru manufacturing; look for PCB, RF, enclosure, EMI/EMC shops in and around the city within our unlisted catalog.
- Diversification: Don’t anchor on a single prime. Spread exposure across adjacent rail-tech verticals—signalling, electrification auxiliaries, power conversion, and safety electronics.
- Liquidity Planning: Unlisted trades can take longer to settle; match your investment horizon to 3–5 year capex cycles rather than quarterly catalysts.
- Scenario Analysis: Run downside cases (award delays, slower standardization) and upside cases (corridor bundling, export possibilities).

Frequently Asked Questions (Investor & Project Focus)
1) What exactly did BHEL win?
A ₹22.87 crore KAVACH order from South Western Railway to design, develop, supply, install, trial and commission on-board and trackside equipment, to be completed in 18 months and manufactured in Bengaluru.
2) Is this a big contract for BHEL?
It’s strategic more than large. BHEL handles much bigger EPC/energy orders, but KAVACH contracts expand safety-tech credentials and future pipeline potential.
3) Why does KAVACH matter to investors in unlisted shares?
Because safety rollouts pull demand for components and services across smaller, often unlisted vendors—electronics, software, field services—who supply primes and PSUs.
4) How long before revenue recognition?
Typically spread across engineering, FAT, installation and commissioning milestones. Smaller suppliers may recognize revenue earlier on hardware deliveries.
5) Is KAVACH expanding beyond SWR?
Yes. Multiple zones and PSUs have announced awards in 2025, pointing to broadening deployments and a multi-year capex cycle.
6) How do I find rail-tech unlisted opportunities on your platform?
Filter by Sector → Rail & Mobility Tech, then shortlist by customer mix, order book clues, and margins. Request verified vendor quotes directly.
7) What risks should I consider in unlisted shares?
Lower liquidity, transfer restrictions, limited disclosures, and issuer policy constraints. We detail these in each issuer note and surface lock-in/ROFR flags pre-trade.
8) How does your escrow process work?
Funds move into escrow; we verify demat transfer off-market; once confirmed, funds are released. You receive contract notes and a full audit trail.
9) I’m a vendor. How do I list inventory?
Apply via Vendor Partner Program. After KYC and holding verification, you can list blocks, set offer ranges, and access priority investor funnels.
