 Although a number of the Green Line surface stops were upgraded with slightly raised platforms around 2003 to allow level boarding on Type 8 low-floor trams, Blandford Street was not among them, and it is not accessible.The Commonwealth Avenue line was originally served by surface streetcars beginning in 1896 as part of what would later become the Green Line A branch.On October 3, 1914, the Boylston Street subway was opened to the Kenmore Portal just east of Kenmore Square, allowing streetcars to enter and run underground into the Tremont Street subway.
