The last El in Boston. Type 7 at North Station about a month before the last elevated in Boston was abandoned and demolished in favor of a new route underground.
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.
