A woman suffered what appeared to be minor injuries Friday afternoon when her motorized wheelchair rolled into the Metro tracks at Eastern Market.

The woman accidentally fell onto the inbound tracks around 4:25 p.m., according to Metro spokesman Philip Stewart. The fall was not intentional and no trains were coming at the time, he said.

The woman had a possible injury to her arm but was expected to recover. Authorities helped her from the tracks.

Trains were forced to share a single track from Federal Center SW to Potomac Avenue stations for about 30 minutes while power was cut to the tracks during the rescue.

The woman was at least the third person in a wheelchair to fall into the system's tracks in less than two years. In December, a man in a motorized chair was rescued by fellow riders when he fell at the nearby Potomac Avenue station. And in November 2010, a man in a motorized wheelchair was saved by riders at the Anacostia station.
