Week 48 of 2015 shows same week total rail traffic (from same week one year ago) declined according to the Association of American Railroads (AAR) traffic data. Intermodal traffic squeaked into expansion year-over-year, which accounts for approximately half of movements and weekly railcar counts continued deeply 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).
