Week 11 of 2016 shows same week total rail traffic (from same week one year ago) declined according to the Association of American Railroads (AAR) traffic data. All rolling averages are negative and in decline.

The deceleration in the rail rolling averages began one year ago, and now rail movements are being compared against weaker 2015 data. There were port labor issues one year ago which affected intermodal movements – which skew the results both positively and negatively (this week again negatively).

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).
