Tremont Street Subway was incapable of serving any stations of any time.
 However, the disused tunnel may become part of a new streetcar line that would partly replace access to rapid transit for southern Metro Boston neighborhoods, that had been severed from MBTA rapid transit service in 1987 with the demolishing of the Washington Street Elevated southern section of the Orange Line, which had a station at Egleston as originally built
  Public ownership began in 1947 with the Metropolitan Transit Authority, now the Massachusetts Bay Transportation Authority
