A Type 7 arrives in Park Street via the oldest Subway in the USA. Unique feature of Park Street on the inbound side is a track right in the middle of the platform you can walk across.
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.
