Why are American freight trains so incredibly long?

Some freight trains in the United States can stretch for miles. For railroads, longer trains can mean greater efficiency and lower operating costs. But once a train reaches that scale, the effects don’t stay on the tracks.

In this video, we look at why American freight trains became so long, how the economics behind them work, and what happens when those trains pass through towns and block road crossings — including the challenges they can create for drivers and emergency responders.

The question isn’t just whether longer trains are more efficient.

It’s: efficient for whom?
