Yes, indeed, a scheme to extend the Red Line through Arlington and into Lexington toward 128 got as far in the 1980s as discussions of massive federal funds for the project.

Opposition from Arlington residents doomed the whole affair, though the tunnels into that town remain and are sometimes used for train storage.
