Railroad Stocks: Which One Actually Wins the Sector?

Wabtec, which builds and services locomotives, scores 9 out of 10 in my quality screener. Union Pacific and CSX, which operate the rails themselves, both cap out at 4 out of 10. The actual railroad business, capital-intensive and leveraged, doesn't pass my criteria well; the company selling it equipment does.

One sector, two very different businesses

When you think railroads, you picture the big operators who own the tracks and run freight trains across the country. Union Pacific and CSX are those operators: they own the infrastructure, run it, and charge for hauling containers, coal, grain, or chemicals. Wabtec, on the other hand, owns no track at all: it's a supplier that designs, builds, and services the locomotives and digital systems these same operators use. Three companies in the same sector, but two nearly opposite business models.

Wabtec: 9 out of 10, a supplier that captures the value

Wabtec passes 9 of my 10 quality criteria: solid profitability (10.5% net margin), excellent return on invested capital (22.1%), and above all, revenue growing faster than costs, a rare sign of operational discipline. The company just signed two major contracts in 2026 that illustrate this pricing power: $1.2 billion with Union Pacific to modernize 1,700 locomotives (24% of its fleet), and $670 million with CSX for 100 new locomotives and 50 modernized units. These contracts promise concrete gains to the operators (up to 80% more reliability, 5% fuel savings), which explains why both rail giants are willing to pay up for this technology.

Union Pacific and CSX: the reality of a capital-intensive business

Union Pacific and CSX each score 4 out of 10. Their common trait: owning and maintaining thousands of miles of track is extremely expensive, year after year, which weighs heavily on return on invested capital (8.8% for Union Pacific, only 4.6% for CSX, well below the threshold I require). CSX also carries high debt (9.67 times its available cash) and margin compression: its costs are growing faster than revenue, a genuine warning sign. Union Pacific, larger and more efficient, fares a bit better on that last point, but its growth remains very low (1.4% sales growth a year over 5 years), a sign of a mature sector that's barely expanding anymore.

What this contrast reveals about my screener

This trio nicely illustrates a rule I see regularly: within a value chain, the most profitable company isn't always the one you'd picture first. Owning physical infrastructure (the tracks, the switching yards) looks impressive, but imposes a permanent maintenance and capital burden that crushes profitability. Selling equipment and services to whoever owns that infrastructure, on the other hand, captures a good share of the value without carrying the weight of the locked-up capital.

The price: Wabtec expensive, the operators cheap on paper

The usual paradox holds on price too. Wabtec trades at 31.4 times its annual cash flow, a stretched multiple my model even flags as 39.6% overpriced at the current price: quality comes at a cost. CSX, by contrast, trades at only 49.9 times... actually a very high figure too despite far lower quality, because its cash generation is thin relative to its size. Union Pacific trades at 30.1 times, an intermediate level. None of the three stands out as an obvious bargain today: Wabtec's quality carries a real price tag, and the operators' seemingly reasonable prices hide fundamentally weaker profitability.

What to remember before investing in this sector

If you want exposure to the US railroad sector, the question isn't "which one is bigger" but "which one actually captures the value the system creates." On that basis, Wabtec remains the fundamentally stronger option, but its price leaves little room for error. Both operators, despite well-known brands and near-monopoly regional positions, remain structurally less profitable once the weight of capital is taken into account.

FAQ

Why does Wabtec score better than the railroad operators it supplies?

Wabtec doesn't carry the burden of maintaining thousands of miles of track. It sells high-value equipment and services, which allows a return on capital far above that of the operators who own the infrastructure.

Are Union Pacific and CSX bad companies?

No, they hold near-monopoly regional positions that are profitable in absolute terms. But relative to the capital they must lock up to operate, their return on investment remains structurally weaker than a supplier like Wabtec.

Do the 2026 contracts with Wabtec change things for Union Pacific and CSX?

These modernization contracts promise real efficiency gains (reliability, fuel) for both operators, but represent a significant short-term capital expense, without changing the capital-intensive nature of the business.

Should you buy one of these three stocks today?

Wabtec offers the best fundamental quality but costs more. Both operators look cheaper on paper but their actual profitability is weaker. This is not personalized investment advice, do your own research.

About the author

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
