Week 39 of 2015 shows same week total rail traffic (from same week one year ago) and monthly total rail traffic (from same month one year ago) declined according to the Association of American Railroads (AAR) traffic data. Intermodal traffic moderately expanded year-over-year, which accounts for approximately half of movements. but weekly railcar counts continued in contraction.

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).
