Weekly "cars on line" 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 data on the average (daily) number of cars on line, broken out by car type such as "box," "covered hopper," "gondola," "intermodal," "multilevel (automotive)," "open hopper," "tank," and "other." According to the STB, "each railroad shall average its daily on-line inventory of freight cars. Articulated cars should be counted as a single unit. Cars on private tracks (e.g., at a customer’s facility) should be counted on the last railroad on which they were located. Maintenance-of-way cars and other cars in railroad service should be excluded."

The dataset contains quarterly and annual grain transportation costs and total landed costs for shipping corn, wheat, and soybeans from Minnesota, North Dakota, and Kansas from the U.S. Gulf and Pacific Northwest to Japan. The data specifically show rail, ocean, barge, and trucking rates for shipping grain to Japan. The total landed costs include transportation costs and farm values for each grain

This dataset contains the annual volumes of major commodities transported by barge, measured in ton-miles. The data is from the U.S. Army Corps of Engineers' Waterborne Commerce Statistics.

This data set contains rail tariff rates for DDGS by railroad, and train type, for select origin/destination pairs. These data are collected monthly from individual railroad websites.

This data set contains rail tariff rates for ethanol by railroad, and train type, for select origin/destination pairs. These data are collected monthly from individual railroad websites.

Bulk vessel size and capacity in million deadweight tonnages. This data contains bulk vessel fleet in numbers and deadweight tons capacity, per year and by type of vessels.

The container vessel fleet dataset provides the number and capacity of the global container vessel fleet as provided and collected by Drewry, Drewry’s Shipping Insight

The data represents total U.S. grain movements involving barge, rail and truck by commodity and market type; starting from 1984.

Weekly "cars held" data from the Surface Transportation Board's (STB) Rail Service Metrics. As part of their submission to the STB, railroads provide data on the average daily number of loaded and empty cars, operating in normal movement and billed to an origin or destination, which have not moved in more than 48 hours. The data is broken out by service type: intermodal, grain, coal, crude oil, automotive, ethanol, fertilizer, or all other. In order to derive the daily averages for the reporting week, carriers are requested to run a same-time snapshot each day of the reporting week, capturing cars within each category that have not moved in 48 hours or more. The number of cars captured on the daily snapshot for each category should be added, and then divided by the number of days in the reporting week (typically seven days). In deriving this data, carriers should include cars in normal service anywhere on their system, but should not include cars placed at a customer facility; in constructive placement; placed for interchange to another carrier; in bad order status; in storage; or operating in railroad service (e.g., ballast).

Fertilizer is defined by the following 14 Standard Transportation Commodity Codes (STCCs): 2871236, 2871235, 2871238, 2819454, 2812534, 2818426, 2819815, 2818170, 2871315, 2818142, 2818146, 2871244, 2819173, and 2871451. STCC 287 covers agricultural chemicals and STCC 281 covers industrial inorganic or organic chemicals (excluding pesticides).

Weekly grain car orders (for manifest service) data from the Surface Transportation Board's (STB) Rail Service Metrics. As part of their submission to the STB, railroads provide data on the running totals of grain car orders placed versus grain car orders filled by State for cars moving in manifest service (as opposed to unit train service). In addition, STB requests the railroads report the number of unfilled orders that are 1-10 days overdue and 11+ days overdue, as measured from the due date for placement under the carrier’s governing tariff.

"Grain" includes the following Standard Transportation Commodity Codes (STCCs): 01131 (barley), 01132 (corn), 01133 (oats), 01135 (rye), 01136 (sorghum grains), 01137 (wheat), 01139 (grain, not elsewhere classified), 01144 (soybeans), 01341 (beans, dry), 01342 (peas, dry), and 01343 (cowpeas, lentils, or lupines).
