MTA System
This is from the back cover of the Boston Rapid Transit Album, a Boston Street Railway Assn, Inc. publication. It shows the MTA, as the T was known, in the 1940s and 50s. Note the different colored lines: today's Red Line was blue, today's Orange Line was red, and today's Blue Line was orange. The current colors were switched during a system wide rebranding when the MBTA was created (this rebranding also gave us the "T" logo we know and love).
