MBTA officials reopened Copley Station at the start of service Wednesday morning.
Trains had last stopped at the busy Green Line subway station on Sunday, April 14.
The station closed for Marathon Monday, as it traditionally does for the race, and remained closed for eight days after because the area surrounding the station's entrances and exits became a massive crime scene after two bombs exploded near the marathon finish line.
Residents and businesses began to be allowed back into the Copley Square area on Tuesday. The are fully-reopened early Wednesday morning.
Copley Station ranks as the 10th busiest in the T's system, according to the agency's most-recent count. The figures, tallied during 2009, show that an average of 13,500 entrances were recorded on a typical weekday.
Only one Green Line station, Park Street, is busier. That station recorded an average of 19,836 entrances on a typical weekday in 2009, according to the T.
