A set of 01600 cars built in 1970 cross the peak of the Longfellow Bridge. These are due to retirement as the new CRRC cars come on line. This bridge was recently rebuilt in the last years.
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.
