A woman also waiting for the train was surprised as well by the large animal, which narrowly missed the train as it came into the station.
Luckily, the deer was fast as it missed all oncoming trains through the station.
The Crystal City Metro Station is in a non-rural part of suburban D.C., but metro officials think it came from a wooded area between National Airport and Crystal City stations, The Washington Post reported.
Deer are usually seen at the outdoor stations in the suburbs, but not that often in a tunnel or an underground station, a Metro spokesperson told the newspaper.
Trains were slowed down while the deer was running around.
It ended up leaving the station using the them, heading toward Reagan Airport, SB Nation reported.
Maybe the deer had to catch a flight to get away from the Caps fans and the celebration parade. We bet it was rooting for the Las Vegas Knights or even maybe the Caps’ rivals, the Pittsburgh Penguins.
