Rail Carloadings

internal.agtransport.usda.gov | Last Updated 26 Mar 2020

Weekly carloads from the Surface Transportation Board’s (STB) Rail Service Metrics. Each week, the seven Class I railroads submit originated and received carloads by 23 major commodity groups, such as grain, grain mill, primary forest products, chemicals, coal, containers, trailers, etc. While the STB began collecting some service metrics from railroads (e.g., trains speeds, origin dwell, and terminal dwell) in October 2014, it did not start collecting carload data until March 2017 through a new rulemaking.

WeekweeknumberWeek number calculated from the reported week ending date (Date field). Week 1 is the first week of the year with a week ending date falling on or after January 4. In other words, it is the first reported week of data which includes four days in the new year. Values range from 1 to 52 or 53, depending on the year.
MonthmonthnumberMonth number calculated from the reported week ending date (Date field). Week ending dates falling before the fourth day of the month are assigned to the previous month. For example, a week ending date falling on February 1st, 2nd, or 3rd would correspond to “1” (January), since there are less than four days in the reported week that fall in February. Values range from 1 through 12, where 1 refers to January, 2 to February, etc.
YearyearnumberYear number calculated from the reported week ending date (Date field). Week ending dates falling on or after January 4 correspond to the calendar year of the reported week. Week ending dates falling on or before January 3 correspond to the previous calendar year. For example, a week ending date falling on January 2, 2018 would be “2017.” Values range from 2017 (partial year) to the present.
