The city under siege has a new bureaucratic hierarchy: The more daunting the barricades in front of a building, the more important it is. Union Station can’t compare with the Capitol, for example, but it trumps the Smithsonian Castle. The installation of 80 cement barricades around the train station has transformed its once fast-paced pickup and drop-off point into a maze, which becomes especially challenging during rush hour and weekend evenings. “In the time it takes you to drive around the building and wait, you could already be where you’re going,” says Zulfigar Ali, a 15-year District cabbie. “It does nothing to protect the building.” “It’s a Band-Aid type of solution to give people the impression they’re doing something,” agrees Amaka Gossett, a part-time sales associate who works inside the station at Political Americana. And it’s an impression the Amtrak Police don’t plan to change, according to Lt. Mike Watson. —Julie Wakefield
