Amtrak just had its 40th birthday, and like many 40-year-olds, it is a diminished version of what it once was. It's still hanging on, and some lines have even been restored over time, in part thanks to the efforts of the National Association of Railroad Passengers (who made these maps for Greater Greater Washington). But is it any wonder more people don't take rail, when coverage has shrunk like a scrotum in a cold pool?
