How Fast Do Freight Trains Go? Average & Maximum Speeds

Quick answer

Freight trains commonly operate well below their maximum permitted speed. In the U.S., track class, railroad rules, signals, curves, grades, congestion, train type and temporary restrictions all affect how fast a freight train can go.

Track class sets an upper limit

Under FRA track standards, Class 3 track permits freight speeds up to 40 mph, Class 4 up to 60 mph and Class 5 up to 80 mph. A railroad may impose lower operating speeds.

Maximum is not average

A train may spend substantial time below the maximum because of grades, curves, meets, signals, yards, congestion or slow orders.

Different trains have different priorities

Time-sensitive intermodal trains may be scheduled differently from heavy bulk trains, but every movement remains subject to route and operating restrictions.

What is the average speed of a freight train?

There is no single nationwide speed that describes every freight train. A train may run faster on open main line, then lose time to signals, meets, yards, grades, curves, congestion and slow orders. That is why a train’s end-to-end average speed can be much lower than its highest speed while moving.

How fast can freight trains go in the United States?

Federal track standards set maximum freight speeds by track class. For example, Class 3 track permits freight operation up to 40 mph, Class 4 up to 60 mph and Class 5 up to 80 mph. Those are upper limits; railroads can and often do require lower speeds for a particular route, train or location.

Why do cargo trains sometimes move slowly?

Heavy tonnage, steep grades, sharp curves, work zones, terminal areas, signal indications and traffic ahead can all reduce speed. Train handling also matters: a long, heavy train must be controlled carefully to manage braking distance and forces between cars.

Freight speed vs. passenger speed

Passenger trains are often authorized for higher speeds than freight trains on the same class of track. Freight trains are generally heavier and may have different braking, handling and operating requirements, so comparing a freight train with a passenger train requires more than looking at the locomotive horsepower.
