It’s a good Saturday for Metro this weekend: Every single line is running on its normal weekend schedule for most of the day (three lines will run slow after 10 p.m.). So if you’ve got lots of Saturday plans around the city, you can actually depend on some timeliness from your friendly neighborhood transit agency.

But things look more familiar starting on Sunday, when the Red Line, the Blue Line, and the Yellow Line will all be running slow. The Blue and Yellow lines will be particularly bad, with trains running 24 minutes apart. The Red Line will be running either eight minutes apart, or 16 minutes apart, depending on where you are along the line. There will be grout pad renewal and track maintenance happening on these lines, according to Metro.

Here’s more detail from WMATA:
