Week 14 of 2017 shows same week total rail traffic (from same week one year ago) improved according to the Association of American Railroads (AAR) traffic data. The economically intuitive sectors declined.
Analyst Opinion of the Rail Data
We review this data set to understand the economy. If coal and grain are removed from the analysis, rail over the last 6 months been declining around 5% – but this week declined 2.1 % (meaning that the predicitive economic elements declined year-over-year). Also consider rail movements are below 2015 levels – even though they are above 2016 levels.
The following graph compares the rail economically intuitive sectors vs. total movements:
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 and intermodal combined).
| Percent current rolling average is larger than the rolling average of one year ago | Current quantities accelerating or decelerating | Current rolling average accelerating or decelerating compared to the rolling average one year ago | |
| 4 week rolling average | +7.2 % | accelerating | accelerating |
| 13 week rolling average | +5.0 % | accelerating | accelerating |
| 52 week rolling average | -2.2 % | accelerating | accelerating |
A summary of the data from the AAR:
The Association of American Railroads (AAR) today reported U.S. rail traffic for the week ending April 8, 2017.
For this week, total U.S. weekly rail traffic was 513,022 carloads and intermodal units, up 7.1 percent compared with the same week last year.
Total carloads for the week ending April 8 were 252,056 carloads, up 9.8 percent compared with the same week in 2016, while U.S. weekly intermodal volume was 260,966 containers and trailers, up 4.6 percent compared to 2016.
Five of the 10 carload commodity groups posted an increase compared with the same week in 2016. They included coal, up 29 percent to 75,078 carloads; grain, up 26 percent to 23,778 carloads; and nonmetallic minerals, up 7.6 percent to 37,582 carloads. Commodity groups that posted decreases compared with the same week in 2016 included petroleum and petroleum products, down 15.7 percent to 10,020 carloads; metallic ores and metals, down 1.4 percent to 20,941 carloads; and forest products, down 1 percent to 9,929 carloads.
For the first 14 weeks of 2017, U.S. railroads reported cumulative volume of 3,576,158 carloads, up 6 percent from the same point last year; and 3,648,646 intermodal units, up 1.7 percent from last year. Total combined U.S. traffic for the first 14 weeks of 2017 was 7,224,804 carloads and intermodal units, an increase of 3.8 percent compared to last year.
Coal is over 1/3 of the total railcar count, and this week the EIA says coal production is 19.9 % higher than the production estimate in the comparable week in 2016.
The middle row in the table below removes coal and grain from the changes in the railcar counts as neither of these commodities is economically intuitive.
| This Week | Carloads | Intermodal | Total |
| This week Year-over-Year | +9.8 % | +4.6 % | +7.1 % |
| Ignoring coal and grain | -2.1 % | ||
| Year Cumulative to Date | +6.0 % | +1.7 % | +3.8 % |
