Weekly origin dwell time data from the Surface Transportation Board’s (STB) Rail Service Metrics. The STB began collecting service metrics from railroads in October 2014. As part of their submission to STB, railroads provide "weekly average dwell time at origin for loaded unit train shipments sorted by grain, coal, automotive, crude oil, ethanol, and all other unit trains. For the purposes of this data element, dwell time refers to the time period from release of a unit train at origin or interchange location until actual movement by the receiving carrier. The data is to be reported by the receiving carrier."

Weekly terminal dwell time data from the Surface Transportation Board’s (STB) Rail Service Metrics. The STB began collecting service metrics from railroads in October 2014. As part of their submission to the STB, railroads provide average terminal dwell time, measured in hours, excluding cars on runthrough trains (i.e., cars that arrive at, and depart from, a terminal on the same through train) for the carrier’s system and its 10 largest terminals in terms of railcars processed. (Terminal dwell is the average time a car resides at a specified terminal location expressed in hours.)

Query from the rail terminal dwell times dataset to include only the latest week of data. Additionally, this view also uses all years of the terminal dwell data, but only the current month of each year, to compute an average and standard deviation of terminal dwell time for each yard and provide a sense of seasonal normal levels.
