Thompson Square station opened on May 22, 1902, almost a year after the rest of the
Charlestown Elevated line, as an
infill station. On December 5, 1960, the MTA began operating "
modified express service" on the Elevated during the morning rush hour. Every other train bypassed Thompson Square and three other stations. This was discontinued in September 1961 to reduce wait times at the skipped stations, all of which were outdoors. It was closed in 1975, when the line was rerouted into a tunnel that was constructed as part of the
Haymarket North Extension project. ==References==
