Orange Line on the Edward Dana Bridge
A train lead by 1516 crosses the Edward Dana Bridge over the Mystic River between Medford and Somerville.
Edward Dana was once known locally as "Mr. MTA". He served as General Manager of both the Boston Elevated Railway and the Metropolitan Transit Authority from August 7, 1919 until his retirement on July 30, 1959. He started working for the BERy in 1907 working as a streetcar conductor, got his education at Harvard University, and worked his way up the ranks.
For decades, Mr. Dana was the heart and soul of the Boston transit system, ultimately topping off his stellar career with the conversion of the Boston & Albany's Highland Branch to "rapid transit" which opened on July 4, 1959.
He may or may not have known it at the time, but for all intents and purposes, he invented the mode of transportation we now call "Light-Rail". Most historians consider the Riverside Line the first "modern" example of the mode.
