By noon Tuesday, more than 351,000 people had ridden Metro, the transit agency said, and it’s a safe bet that a vast number of them used the system to attend the Capitals’ victory party and parade downtown.

That figure is up more than 78,000 from the same time period on Monday, officials said.

Metro is running rush-hour levels of service throughout the day to help deal with the crowds attending the Capitals celebration.

The agency said it had not had any problems with its tracks or trains so far (knock on wood).

At 9:30 a.m., Metro said many of its parking lots and garages in Maryland and Virginia were full. The full lots included: Branch Avenue, East Falls Church, Forest Glen, Fort Totten, Grosvenor, Morgan Boulevard, Rockville, Rhode Island Avenue, Shady Grove West and Wiehle-Reston.

Metro spokesman Dan Stessel said there had been no major problems despite the crowds. The transit agency is running rush hour service until 7 p.m.  so trains will operate about every eight minutes from the stations at the end of the line.

Still, riders should be patient: At least 100,000 people were expected at the Capitals’ celebration and parade.

On the roads, there were no reports of serious crashes on any major highways or secondary streets. Many commuters found traffic to be lighter than on a normal work day.
