The South End is currently serviced by the Silver Line but for long-time residents and those who called the South End there home up through the 1980s they will recall this line which stopped running in 1987. The image above is courtesy of the blog, AloneOne. In the image above you can see the cathedral on Washington Street in the background. Much has changed in the nearly 20 years since the elevated Orange Line stopped running and the Silver Line was created to serve this neighborhood. The image to the left (click it to enlarge)offers a glimpse of what Washington Street in the South End looks like now and includes a picture of the Silver Line bus service which residents now rely on to get to and from downtown.
However, if you are nostalgic about the old Orange Line check out Alone One's tribute on his blog by linking here. He even has a five or six minute video you can watch and listen to.
