To accommodate a Veterans Day concert on the National Mall, Metro closed down the Blue Line and replaced trains with Yellow Line service. This was done based on a prediction that up to 800,000 people would attend, a crowd larger than most Presidential inaugurations and Fourth of July celebrations.

“This one has kind of come up on us late in the game,” outgoing Metro General Manager Richard Sarles told News4. “I think it just requires us to scramble faster, to plan faster. But our customers need to have a certain level of expectation.”

While the Concert for Valor was attended by thousands, the crowd was nowhere near the 800,000 predicted. This can be seen in the above chart created by PlanItMetro, which shows that ridership was essentially the same as a typical workday.

The only different spike in Metrorail entries can be seen 10 p.m., when the concert ended. But that number was lower than morning and evening commuter numbers on a typical workday. From PlanItMetro:

Ridership from the Concert was clearly visible at stations on the National Mall (L’Enfant Plaza, Archives, Gallery Place, Metro Center, Federal Triangle, and Smithsonian). Following the concert ending, these stations handled over 36,000 passengers in 90 minutes – twice the volume of a typical weekday, and all crowds had been accommodated by 11 p.m.
