I have been researching the T.. specifically the old branches. The "A" line that went to Watertown, the branch after Boylston that went down Pleasant St, the old ELEVATED ORANGE LINE!! which is total silliness. And I thought I remembered, from the first time I ever went to the Garden/Fleet Center the raised subway tracks. So vividly I remembered them.. because they amazed me.
These tracks were in use until 1997 which is a little after the first time I ever came to Boston. Yes! My memory has not failed me.!!!
