Class I Railroad in Shipping

What is a Class I Railroad?

A Class I railroad is a freight railroad in the highest revenue class used by the US Surface Transportation Board (STB). Railroads are grouped into Class I, II and III by their annual operating revenue. The STB sets the Class I revenue threshold and adjusts it for inflation every year; it is roughly $1 billion today.

Only a handful of very large carriers qualify, such as BNSF Railway, Union Pacific, CSX and Norfolk Southern. Canadian National and CPKC also operate as Class I railroads in the US. Smaller regional (Class II) and short-line (Class III) railroads connect to their networks.

Significance of Class I Railroads in E-commerce Shipping

• Long-haul reach: Class I railroads run the long-distance networks that link major ports, inland terminals and distribution hubs across North America.
• Cost-efficient bulk transport: For large volumes moving long distances, rail intermodal (containers moved by train between trucks) is often cheaper per unit than trucking the whole way.
• Middle-mile capacity: Brands and their logistics partners use rail for the middle mile, for example moving imported containers from a port to an inland warehouse before last-mile delivery.

How Class I Railroads Work in a Shipment

1. A container arrives at a port or is loaded at a shipper’s facility.
2. It is trucked to a rail terminal and loaded onto a Class I train for the long-haul leg.
3. At the destination terminal it is unloaded and trucked to a warehouse or distribution center (drayage).
4. From there, orders are picked, packed and shipped to customers by parcel carriers.

Rail is usually slower than trucking door to door, so it suits inventory replenishment and planned stock moves more than urgent deliveries.

Use Case of Class I Railroads

A brand imports a container of products through the Port of Los Angeles for its warehouse in Texas. Instead of trucking the container about 1,400 miles, its logistics partner books intermodal rail with a Class I railroad to a terminal near Dallas, then a short truck move to the warehouse. The longer transit is planned into the replenishment schedule, and the long-haul leg costs less than trucking it the whole way.
