Week 33 of 2018 shows same week total rail traffic (from same week one year ago) improved according to the Association of American Railroads (AAR) traffic data.

Analyst Opinion of the Rail Data

We review this data set to understand the economy. If coal and grain are removed from the analysis for carloads, this week it expanded 3.3 %. We primarily use rolling averages the analyze the data due to weekly volatility – and the 4 week rolling average for the intuitive sectors slowed from 3.3 % to 2.7 %.

Intermodal transport growth remains strong year-over-year.

This analysis is looking for clues in the rail data to show the direction of economic activity – and is not necessarily looking for clues of profitability of the railroads. The weekly data is fairly noisy, and the best way to view it is to look at the rolling averages (carloads [including coal and grain] and intermodal combined).

A summary of the data from the AAR:

For this week, total U.S. weekly rail traffic was 567,477 carloads and intermodal units, up 3.7 percent compared with the same week last year.

Total carloads for the week ending August 18 were 278,701 carloads, up 2.9 percent compared with the same week in 2017, while U.S. weekly intermodal volume was 288,776 containers and trailers, up 4.4 percent compared to 2017.

Nine of the 10 carload commodity groups posted an increase compared with the same week in 2017. They included grain, up 5,491 carloads, to 23,404; petroleum and petroleum products, up 1,544 carloads, to 10,898; and miscellaneous carloads, up 1,523 carloads, to 10,629. One commodity group posted a decrease compared with the same week in 2017: coal, down 4,534 carloads, to 93,248.

For the first 33 weeks of 2018, U.S. railroads reported cumulative volume of 8,626,033 carloads, up 1.7 percent from the same point last year; and 9,126,732 intermodal units, up 6 percent from last year. Total combined U.S. traffic for the first 33 weeks of 2018 was 17,752,765 carloads and intermodal units, an increase of 3.9 percent compared to last year.
