Bowdoin (pronounced BO-din) of the MBTA, is a station on the Blue Line, serving Bowdoin Square in Boston's Beacon Hill neighborhood. It opened for service on March 18, 1916, and was originally part of an old trolley line that ran under downtown Boston, connecting Beacon Hill to Maverick Square. The station is lightly used except at rush hour, and is only open from 5:15AM to 6:30PM, Monday through Friday, excluding holidays, prior to 2013. At all other times, trains terminate and originate service at Government Center station. The sharp loop just past the station is used to turn around Blue Line trains at all times, sending them back to Government Center and on to Wonderland, in Revere. The platform is wedge shaped, with a single entrance at the fat end, near the turnaround loop.
