Riders will have long waits at stations across the system. (Linda Davidson – The Washington Post)

Metro isn’t closing any stations this weekend, which is a nice change of pace for riders tired of having to stop along their routes, climb out of stations and board buses that take them back into the rail system. But work across the system will cause longer waits at stations on all five lines.

Red Line trains are going to share a track between Shady Grove and Twinbrook and between Rhode Island Avenue and Takoma for rail improvements, platform reconstruction and other work. Trains are going to run every 24 minutes between Shady Grove and Glenmont, but additional trains running between Grosvenor and NoMa on Saturday and Sunday between 9 a.m. and 9 p.m. mean that trains will likely run in that stretch every 12 minutes.

Trains on the Orange, Blue, Yellow and Green lines will all run every 18 minutes because of work zones on all five lines. That covers platform reconstruction between Stadium-Armory (on the Blue and Orange lines) and Cheverly (on the Orange Line), rail work between Mt. Vernon Square and U Street (on the Green and Yellow lines) and Silver Line testing between East Falls Church and West Falls Church (on the Orange Line).

The delays all begin Friday at 10 p.m. and last through the system’s closure Sunday night.
