 This improved performance coincided with a general economic downturn, resulting in the lowest freight-rail traffic volumes since at least 1988, meaning less freight traffic to impede passenger traffic.In 2018, Amtrak began issuing report cards, grading each host railroad based on the railroad's impact on on-time performance.The first report card, issued in March 2018, includes one A (given to Canadian Pacific) and two Fs (given to CN and Norfolk Southern).
