A "furry fare evader" surprised commuters in a Center City Philadelphia underground train station.

PATCO tweeted a photo of a raccoon on the stairs of the transit agency’s 8th Street Station.

"PLEASE NOTE: We're aware of this furry fare evader at 8th Street," the agency tweeted around 6:20 a.m. Tuesday.

The animal was first reported on the platform Monday night, PATCO spokesman Kyle Anderson said.

Animal control officers were called in to safely corral the animal but as of Tuesday morning it remained on the loose, PATCO said.

Trains ran on schedule throughout the morning despite the raccoon stir.

No word yet on how the raccoon wound up in the station. The agency says that animal sightings are more common at its outdoor stations in South Jersey.
