It's not just your imagination—Amtrak really has been delayed more than usual lately. According to the passenger rail corporation's latest monthly performance report, on-time arrival stands at roughly 74 percent for fiscal 2014 (which began in October 2013). That's down nearly 12 points from fiscal 2013, when Amtrak was on-time for 85 percent of its trips.
So what gives? Well, if you look closer at the above chart, you'll notice a clear dip between May and June of 2013. On-time performance fell from 83 percent to 76 percent between those months, and it's remained below the 80 percent-mark ever since.
