Commuters on Metro are facing some hassles Monday morning as the Metro system recovers from Sunday’s whopper storm that knocked out power across the region.

The storm had caused flooding of some rails, blocked tracks with downed trees and zapped power at more than a dozen rail stations, plus Metro rail stations and rail yards.

Much of the service was restored. But the outages prevented crews from doing the scheduled maintenance they normally would overnight, Metro said. They also could not move trains into position for the Monday morning commute, as they focused on restoring power.

What this means for riders: fewer trains in service — and possibly more hot cars. Crews are behind fixing broken air conditioning on cars and getting trains into the right places, according to the transit agency.
