The end of PCC operation was near on the MBTA's C Line (Cleveland Circle/Beacon Street) as this pair departed the Coolidge Corner stop in Brookline on an inbound run.
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.
