Railroad Performance Measures   

Welcome to the Railroad Performance Measures website, where six major North American freight railroads have voluntarily reported three weekly performance measures — Cars On Line, Train Speed, and Terminal Dwell — since 1999, in a commitment to improve communications with their customers:

BNSF Railway Kansas City Southern
CN Norfolk Southern
CSX Transportation Union Pacific

All six railroads use the same definitions to calculate their performance data, ensuring a high degree of consistency of the measurements. However, these measures are most useful for examining trends and relative changes, and least useful as absolutes.

The level of one railroad’s performance relative to another’s may differ sharply because each railroad is unique. Differences between railroads include terrain, physical routes and network design, traffic mix and volume, the extent of passenger operations, and operational practices. External factors such as weather and port operations can also cause variations between railroads and over time. In addition, individual differences in the collection and reporting of operational data may affect the absolute level of the measures on each road to some degree.

Please refer to the Definitions page for an explanation of the measures.


Railroad Performance Measures are published every Wednesday at 2:00 p.m. Eastern Time.
