Arriving in Harvard set of 01800's built by Bombardier roll into the station. At one point this was the end of the red line until the Alewife extension in the 1980's was completed.
The MBTA is very dear to me. The first trains I ever rode as a toddle to teenager were those of the "T" Here is a collection of MBTA Subway and trolley I have found on RP from the 60's thru today.
