You have been on a train. Countless times probably. Delhi to Rohtak, Mumbai to Pune, wherever. You sit, stare outside, maybe scroll some reels. At some point the locomotive pulls out of the station and you feel that smooth surge of power. You never think about what is actually doing that.

Most people assume bullet trains have all the fancy technology and the regular Rajdhani or Shatabdi or local DEMU/MEMU running on boring old electric tracks is just mechanical stuff sorted decades ago. That assumption is completely wrong.

Inside every 6,000 HP electric locomotive hauling your train right now is something called a Propulsion System. It is the brain. It takes the 25,000 volt AC from the overhead wire, chops it, converts it, and feeds perfectly controlled variable frequency power to the traction motors spinning those giant wheels. Without this system your train does not move. Full stop.

And here is where it gets genuinely interesting from an investment standpoint.

The Tech That Runs Indian Railways Has Been Imported For Decades

For the longest time India bought this technology. ABB from Switzerland, Siemens from Germany, Alstom from France. These MNCs supplied the propulsion brains and Indian Railways paid whatever they charged. Not because Railways wanted to, but because nobody in India had cracked it.

Then came Medha Servo Drives from Hyderabad. A 40 year old privately held company that built it from scratch, owns the IP, and today supplies propulsion systems for everything from WAP-7 passenger locos to Vande Bharat trainsets. They are the dominant force. ₹4,300 Crore in revenue in 2025. Quiet, unlisted, profitable.

For years Medha was the only Indian company that owned this technology indigenously. Everyone else either imported or licensed it from European OEMs. And that licensing model is where things get messy. Companies like CG Power and BHEL took technology from foreign players. The moment there is an execution issue or a testing requirement they go back to the European partner for approvals and sign-offs. That dependency creates bottlenecks. Orders slip. Deliveries delay. The foreign partner is not sitting around waiting for your India problem to be solved.

Railways is essentially a captive customer for this technology. They need it. They have to buy it. But they have been quietly desperate to find more Indian alternatives.

A few days back I visited MV Electrosystems in Faridabad. They are going public, ₹290 Crore IPO, mainboard listing on NSE and BSE. The headline claim is something that initially sounds too good to be true. Second Indian company to indigenously develop IGBT-based 3-Phase Drive Propulsion for Indian Railways. RDSO approval received September 2025. Commercial supplies to Indian Railways started March 2026.

I wanted to verify whether this is marketing or reality. So I went.

The company started humble. Promoters began with cable protection systems for railways. Conduits, switchgear panels, basic electrical components. The kind of supplier that nobody writes blog posts about. But they were inside the system, knew the customer, understood the regulatory maze of RDSO approvals. That foundation mattered more than it looks.

Somewhere around 2020 they made a bet. Started building the propulsion system in-house. Hired engineers. Build an R&D centre.

The man behind this entire technology effort is Pankaj Rastogi. He was the Director of Research and Development at MV Electrosystems. Recently elevated to Managing Director after the RDSO approval came through. Classic internal promotion. The guy who built the product now runs the company.

When I sat with him in Faridabad I expected a corporate pitch. Slides, projections, and all. I got none of that. He walked me through the actual technology. The IGBT-based traction converter architecture. The Vehicle Control Unit that manages power delivery, braking, fault detection. The firmware logic that controls everything. He explained it the way an engineer who has lived inside a problem for five years explains it.

What struck me most was the in-house PCB assembly and ECU development. These are the printed circuit boards and electronic control units that are the nervous system of the propulsion controller. Most companies in this space outsource these. MV Electrosystems makes and tests them internally. That is not common for a company their size. It also means they own the IP at every layer, not just the system design.

The IGBT Question

Yes, they import IGBT modules. These are the high power semiconductor switches at the core of the traction converter. The switching elements that handle the actual power conversion.

Here is the reality of that. Globally there are maybe 5-6 companies that make railway grade high-voltage IGBT modules. Infineon from Germany. Mitsubishi Electric from Japan. Fuji Electric. Hitachi Energy. Semikron Danfoss. That is roughly the list. No Indian company makes these at the voltage class required for locomotive propulsion. Not BHEL. Not anybody.

Every Indian propulsion system, including Medha’s, imports these modules. So the import dependency is real but it is not unique to MV Electrosystems. The indigenisation argument is about system design, software, control architecture, and manufacturing. Not about the silicon wafer in the IGBT module itself.

The existing approval and order book of roughly 900 Cr is for 6,000 HP WAP-class locomotives. The conventional ones hauling Rajdhani and Shatabdi trains. Concentrated propulsion meaning one big unit powers the locomotive.

Vande Bharat is distributed propulsion. No separate locomotive. Power electronics under every motor coach, coordinated across the full trainset. Architecturally different problem.

MV Electrosystems does not have Vande Bharat approval yet. But here is what matters. They are not starting from zero on this. The core IGBT control technology, the firmware, the VCU logic, the thermal management, all of that carries over. Developmental orders are already there. Hotel Load Converter developmental orders are in progress too. This is an extension of existing capability, not a fresh invention.

Rastogi sir was measured about the timeline. Not overselling it. That actually made me more confident than if he had given me a roadmap with aggressive dates on it.

So what exactly is the Investment Case?

Here is where it gets genuinely difficult. And I say this having spent time at the facility, met the people, verified the technology.

The company posted ₹49 Crore in revenue in FY26 and a ₹12 Crore loss. The loss makes sense once you understand it. Five years of R&D salaries, IGBT component procurement sitting in inventory ahead of deliveries, new plant capex. The loss is a consequence of investing, not a consequence of failing.

The order book stands at approximately ₹920 Crore as of now. That is 19 times their last year’s revenue sitting as contracted orders from Indian Railways.

The IPO is at north of 1,000 crore market cap.

On trailing numbers this looks absurd. But that is exactly the wrong frame. The right question is whether a company with proven proprietary technology, RDSO approval in hand, and 920 Crore of contracted orders from a sovereign customer can execute.

And that is where the honesty has to come in. No one knows.

Fancy QIBs and anchor investors do not care about the story, they care about the moat. They show up at facilities exactly like I did. They call CLW procurement officials. They verify the purchase orders. They run competing scenarios on working capital adequacy. They check whether Rastogi sir has an employment contract that ties him in for 5 years or whether he can walk out the day after listing.

What they are doing is not sophisticated financial modelling in isolation. They are connecting the ground reality to the spreadsheet. Is the RDSO approval real? Yes, verified. Is the order book real? Verify the POs. Does the team actually understand the technology or is it outsourced?

When enough of those ground level checks come back clean the conviction builds regardless of the trailing P/E ratio.

The valuation ambiguity remains.

The Real Scorecard

Railways is not happy paying Alstom and Siemens whatever they charge. They have been effectively forced to because the domestic supply was thin. Medha alone cannot fulfil all the demand and they have no competitive pressure on pricing. The arrival of a second RDSO approved vendor with indigenous IP is exactly what Railways has been quietly waiting for it seems.

How the stock will perform after listing? genuinely no idea. However, we as a country is clearly moving in the right direction. Whether this specific vehicle at this specific valuation is the right way to participate in that direction, well, that is for each of you to figure out on your own.
