Boston Subway opens.

Originally the Tremont Street Subway, it begins operation just after 6:00 a.m. when a streetcar from Allston enters the Boston Public Garden portal and runs through a 6/10th-mile-long tunnel to the new Boylston Street and Park Street stations. By midnight, some 250,000 people pay the 5-cent fare to ride the first subway in the U.S. and the fourth in the world (after London in 1863, Budapest and Glasgow. Ground was broken on the project on March 28, 1895. During construction, some 900 graves had to be moved from the Central Burying Ground and the excavated dirt was used to raise parts of Boston Common and Public Garden by as much as six feet. The line is extended to Broadway (then Pleasant Street) in 1897,* to Haymarket Station and North Station in 1898,* to Lechmere in 1912, and to Science Park in 1955.*
