How Often Do Train Derailments Happen

Train derailments rarely make the news unless they’re severe, but they happen far more often than most people think. Many happen at slow speeds inside rail yards and cause limited damage. Others occur on mainline tracks, where higher speeds and heavier loads can turn an incident into a major event.

This blog breaks down how often derailments happen in the United States, why they occur, and what they mean for agricultural and industrial sites.


How Many Train Derailments Happen Each Year?

While derailments were far more common several decades ago, the total has flattened in recent years. Modern rail technology, improved inspections, and upgraded track standards have kept totals relatively stable.

Why the numbers remain high:


Where Derailments Happen Most

Derailments occur in two main locations: rail yards and mainline tracks. Understanding the difference helps explain why some incidents cause massive damage while others barely make the news.

Rail Yards (Slow-Speed Areas)

About 74% of derailments occur in rail yards. This is because yards involve:

Yard derailments tend to cause less damage because trains are moving slowly.

Mainline Tracks

Only 25–30% of derailments happen on mainline tracks³, but these are often the most severe. Mainline derailments matter because:

For agricultural areas, many mainline corridors run directly through grain production zones, increasing potential impact.


Why Train Derailments Happen

The Federal Railroad Administration groups derailment causes into several categories. Below are the most common.

Track Problems

Track issues remain one of the leading causes, especially on mainlines where speed makes defects more dangerous.

Common problems include:

These issues worsen during extreme temperature swings, freeze–thaw cycles, and prolonged heat.

Equipment Failure

Mechanical issues account for a significant number of derailments, including:

A single component failure can lead to a major derailment, especially under load.

Human Factors

These are more common in rail yards and switching zones:

Environmental Conditions

Weather plays a direct role in track stability:


How Often Derailments Involve Hazardous Materials

While derailments are common, hazardous material releases are not.

Based on FRA hazmat data:

Hazardous materials include:

Even when no hazmat is released, the presence of these materials still increases risk for nearby farms and facilities.


Why Train Derailments Matter for Farms and Grain Facilities

Agricultural operations are especially exposed to derailment risks because many facilities sit next to high-volume rail corridors.

Trains routinely carry:

This is why derailments, even when infrequent at any one location, must be included in risk and safety planning.


Daily Reality: Train Derailments Happen Constantly

With 3–4 derailments occurring every day² across the U.S., derailments are a routine part of national rail operations. Most are small. But all it takes is one derailment near a farm, grain operation, or industrial site to cause major disruption.


Conclusion

Train derailments happen more often than most people realize. The U.S. sees more than 1,000 derailments per year, and while most are minor, mainline incidents can cause substantial damage, contamination, and operational downtime.
