There was a fight aboard a Red Line train last evening. That much Metro officials and riders can agree on. But accounts differ on whether or not the emergency intercom system was working as intended when riders called for help.

In tweets aggregated by Chris Barnes of Fix WMATA, a woman reported seeing “a huge fight” on the platform of the Woodley Park Metro station, which began on a train. The rider said the emergency intercom button did not appear to be working, as the riders who pressed it did not receive a response from the driver.

The Post spoke to a witness of last night’s fight, who reported seeing a “group of kids” attack another rider:

She said some of the youths were pulling on the rider’s bag, in what she thought might have been an attempt to steal it. The man was punched in the face, and other riders appeared to come to his aid, the woman said.

When the train reached the station, she said, the youths spilled onto the platform with one or two of the passengers with whom they had tangled. The passengers got back on the train, and it continued on.

The female witness said passengers tried to reach the train operator over the intercom, but there was no indication that their attempts were successful, which she called worrisome.

Metro spokesman Dan Stessel wrote in an email, however, that “the train operator was notified via the intercom and notified the control center, who in turn, sent Transit Police to Woodley Park station.

“Metro Transit Police Department identified the two subjects who had been fighting,” Stessel continued. “Neither wanted to press charges and neither was injured. The call was closed with no report.”

When asked about the report of the intercom failure, Stessel replied, “We are aware of that report and will follow up on it.”

Reports of issues with intercom buttons on Metro trains are not new. NBC4 reported in March that there have been 170 intercom malfunctions since 2011.
