Metro to change construction schedule and single tracking
This is big, and will have an effect -- for the better or worse -- for the next year and a half, they're saying. They will be doing less weekend single-tracking, and instead just closing more stations outright and providing shuttle busses. See the Post.
Really big development for DC. I hope they know what the heck they're doing. That's sometimes a big hope with Metro. But I'd like to be optimistic on this.
The single tracking has been a mess ever since the crash in 2009. After that, all trains ran on manual, rather than automatic, and train spacing has been a mess ever since. This becomes a particularly wild problem with weekend single-tracking.
Of course, if this new system works better, the question will become, why didn't they do it earlier.
