Week 46 of 2017 shows same week total rail traffic (from same week one year ago) expanded according to the Association of American Railroads (AAR) traffic data. The economically intuitive sectors remain in expansion and the rolling average growth rate was statistically unchanged.

Analyst Opinion of the Rail Data

We review this data set to understand the economy. If coal and grain are removed from the analysis, this week it improved 4.4 % (meaning that the predictive economic elements improved year-over-year). This week the economically intuitive one year rolling averages continue in expansion for the 25th week - and modestly improved.

Intermodal transport did grew strongly year-over-year this week - which is the economically positive element or rail transport.

The following graph compares the four week moving averages for the rail economically intuitive sectors (red line) vs. total movements (blue line): Rail's intuitive sectors have been bouncing around the zero growth line for most of 2017.

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 554,066 carloads and intermodal units, up 1.2 percent compared with the same week last year.

Total carloads for the week ending November 18 were 266,927 carloads, down 1.6 percent compared with the same week in 2016, while U.S. weekly intermodal volume was 287,139 containers and trailers, up 3.9 percent compared to 2016.

Four of the 10 carload commodity groups posted an increase compared with the same week in 2016. They included metallic ores and metals, up 4,537 carloads, to 23,696; nonmetallic minerals, up 3,675 carloads, to 38,355; and chemicals, up 1,334 carloads, to 31,939. Commodity groups that posted decreases compared with the same week in 2016 included coal, down 8,528 carloads, to 86,185; grain, down 3,841 carloads, to 21,926; and petroleum and petroleum products, down 887 carloads, to 10,184.

For the first 46 weeks of 2017, U.S. railroads reported cumulative volume of 11,969,281 carloads, up 3 percent from the same point last year; and 12,420,150 intermodal units, up 3.7 percent from last year. Total combined U.S. traffic for the first 46 weeks of 2017 was 24,389,431 carloads and intermodal units, an increase of 3.4 percent compared to last year.

Coal is over 1/3 of the total railcar count, and this week the EIA says coal production is 6.2 % lower 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.

For the week ended November 18, 2017

• Estimated U.S. coal production totaled approximately 14.9 million short tons (mmst)
• This production estimate is 0.9% higher than last week's estimate and 6.2% lower than the production estimate in the comparable week in 2016
• East of the Mississippi River coal production totaled 5.7 mmst
• West of the Mississippi River coal production totaled 9.2 mmst
• U.S. year-to-date coal production totaled 694.7 mmst, 8.6% higher than the comparable year-to-date coal production in 2016
