For several years, it was operated by Gore, Rose and Company, owned by David Gore and George Rose, because the original company could not afford to run it.
The Dorchester Avenue Railroad was chartered April 29, 1854, opened in spring 1857, and bought by the Dorchester Railroad (chartered April 29, 1855) in January 1858.
Both were leased to Gore, Rose and Company, which operated the line from June 1, 1858 to 1862.
[1] An 1871 map shows the downtown end continuing from Dorchester Avenue along Federal Street to Dewey Square, and then along Broad Street (now partly Atlantic Avenue) to a terminus at State Street, with no connections to any other lines.
It no longer carries a single service (which would now be bus) because the Red Line subway parallels Dorchester Avenue for its entire length.
