More than 870,000 trips were taken on the Metro system Wednesday, making it the fourth busiest day in the transit agency's history, Metro said.

A Capitol Hill rally, cherry blossoms and the tourists flocking to see them, a Nationals Game and a Wizards game got the credit for the ridership boom.

It was the busiest day for Metro since April 2, 2010, the agency said. The No. 1 day for Metro ridership was President Obama's first inauguration in 2009.

Metro is expecting another busy day Thursday, with more cherry blossom visitors and another Nationals game, as well as a Capitals game. The agency will add additional trains between Mount Vernon Square and Anacostia stations to help shuttle baseball fans.
