In just a few minutes, the eastern branch of the DC Metro's Red Line will close for major overhaul. Having rode the line a few hours ago, nothing seems amiss on the trackbed. This is the trackkeepers' job; to intervene before the bottom falls out. From my engineering-dad's perspective, there will be a fascinating array of work-crews and equipment on the trackbed from 10pm tonight until 5am Tuesday morning. That's 79 hours of intensive care for the tracks that carry hundreds of trains a day.
Most people won't mind, though. They're out of town, far away from the DC Metro and its temporarily truncated service. If all goes well on the tracks this weekend, my Tuesday commute will be a bit better than before.
