Los Angeles Metro riders faced longer commutes Monday after a car crashed through a fence onto the tracks of the Expo Line. Service was disrupted until the car could be towed away. As far as transportation woes go, that was nothing. In Washington D.C. this past March, the city’s Metro service had to shut down for the entire day, leaving hundreds of thousands of commuters stranded. The shutdown was so traumatic, #Metropocalypse trended on social media. As it turns out, subway systems throughout the Northeast are crumbling. Service interruptions are routine for riders in New York and Boston where, unlike Los Angeles, their subway systems are old and in major need of repairs – to the tune of billions of dollars.
