So the WMATA board meets tomorrow to discuss a repair plan, then the public will find out next week.
Rumors are...well, out of control. There have been leaks, whispers, theories, guesses.
Some combination of the below is expected to happen:
1) Hours will be drastically cut (perhaps even digging into rush hour, perhaps running trains rush hour only)
2) Service will be drastically cut (i.e. weeks of single-tracking, and maybe shorter trains)
3) Entire lines will shut down for X number of weeks (possibly months)
4) Only the Orange and Blue Lines will be seriously impacted (WMATA implied this themselves a week ago)
5) Each line will shut down for X weeks/months on a sort of rotating schedule
6) Some stations will be bypassed for X weeks/months (stations affected by this rumor include the entire Medical Center-Tenleytown stretch of the Red, and McPherson on the Blue, the gaps will be filled by bus connections)
No matter what, though, it's going to be a shitfest. That much is certain. Metro has to come up with a plan, and they have to enact it, and it will be drastic. At the current operating level, Metro says it'll "take years" to catch up to the safety standards they've been ordered to get up to.
