Railroad

A railroad is a company that operates a network of railway tracks to transport freight and, to a lesser extent, passengers. In the world of investing, railroads are titans of the “old economy”—massive, capital-intensive businesses that form the steel backbone of a nation's commerce. They are quintessential infrastructure assets, moving everything from the grain in your bread to the car in your driveway. For value investors, railroads are particularly fascinating. Their business model is a textbook example of a deep, durable economic moat, a competitive advantage that is incredibly difficult for a competitor to overcome. Legendary investor Warren Buffett made one of his largest-ever acquisitions by buying the BNSF Railway, famously calling it an “all-in wager on the economic future of the United States.” This highlights their role as a bellwether for the economy; when railroads are busy, it's a strong sign that goods are being produced and consumed, and the economy is humming along.

Why do shrewd investors find these century-old businesses so appealing? It boils down to a few powerful, interlocking advantages.

Imagine trying to start a new railroad company to compete with an established player. You would need to spend hundreds of billions of dollars to buy land, lay thousands of miles of track, blast through mountains, and build bridges. The sheer cost and the logistical nightmare of acquiring the necessary land, known as the right-of-way, make it practically impossible to replicate an existing rail network. This creates one of the most formidable barriers to entry in the entire business world. Existing railroads don’t have to worry about a scrappy startup popping up to steal their customers.

The North American railroad industry is a classic oligopoly, meaning it is dominated by a small number of very large players. The landscape is controlled by a handful of “Class I” railroads, such as Union Pacific Railroad, CSX Transportation, Canadian National Railway, and Canadian Pacific Kansas City. With so few competitors in any given region (often only two, creating a duopoly), they face limited direct competition for long-haul freight. This structure gives them significant pricing power, allowing them to raise prices consistently over time, often above the rate of inflation, which is a wonderful characteristic for a long-term investment.

For moving heavy goods over long distances, nothing beats a train. A single train can haul the equivalent of hundreds of trucks, and railroads can move one ton of freight over 400 miles on a single gallon of fuel. This makes them far more cost-effective and environmentally friendly than trucking for many types of cargo. This is a durable competitive advantage that is unlikely to change. As long as a modern economy needs to move physical goods, it will need railroads, making their business model incredibly resilient.

Despite their strengths, investing in railroads isn't a one-way ticket to riches. There are significant risks to consider.

• Economic Sensitivity: Railroads are highly cyclical. When the economy slows down into a recession, manufacturing activity declines, construction stalls, and consumers buy less. This leads to a direct drop in shipping volumes and, consequently, railroad revenues and profits.
• A Thirst for Capital: Maintaining a vast network of tracks, bridges, tunnels, locomotives, and railcars is enormously expensive. Railroads have massive, recurring capital expenditures (CapEx) just to maintain the status quo. Investors must look past the headline earnings and focus on free cash flow—the cash left over after these huge maintenance costs are paid.
• Regulation and Labor: As essential infrastructure, railroads are subject to significant government oversight. In the U.S., the Surface Transportation Board can influence rates, approve mergers, and mandate service levels. Furthermore, railroads are heavily unionized, and labor disputes can lead to costly strikes that paralyze operations.

When analyzing a railroad company, professionals focus on a few key performance indicators to judge its efficiency and profitability.

• Operating Ratio (OR): This is the single most important metric for a railroad. It measures operating expenses as a percentage of revenue (Expenses / Revenue). A lower OR is better, as it indicates a more efficient and profitable operation. Watching the trend of a railroad's OR tells you a lot about its management's skill.
• Volume and Pricing: Investors track volumes through metrics like carloads and intermodal units. They also watch revenue per ton-mile to see if the railroad is successfully using its pricing power.
• Return on Invested Capital (ROIC): Because railroads employ a gigantic amount of capital (tracks, trains, etc.), return on invested capital is a crucial metric. It tells you how effectively management is generating profits from the company's massive asset base.

Railroads are fantastic, durable businesses with wide economic moats that can make for excellent long-term investments. They are a pure play on the long-term growth of the economy. However, they are not fast-growing tech stocks. They are capital-intensive, cyclical giants that require patience. For the value investor, the key is to understand the business, respect its cyclicality, and, as always, buy a wonderful company at a fair price, not a fair company at a wonderful price.
