Freight Commodity Statistics Database File

The Class I railroads report statistical information to the AAR, which after processing the statistical information, makes the data available to the Surface Transportation Board and the Federal Railroad Administration. The agency used these data to prepare reports on railroad freight traffic.

This series consists of quarterly Class I railroad traffic statistical information. For each Class I railroad for each quarter, the traffic statistics include the number of carloads and tons by commodity group (Standard Transportation Commodity Code) of freight originated and terminated, freight originated and delivered to another carrier, freight received and terminated, freight received and delivered to another carrier, and total freight carried.
