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.
A timeless scene still seen today, a PCC crosses Capen Street in this peaceful part of Milton. Trolleys stop for a stop sign clang bells making sure the road is clear then move on.
A quirky bit of the T is the High speed trolley line from Ashmont to Mattapan with 70 year old PCC cars. Intended as a "trolley freeway" now lives on as a link to Ashmont from Mattapan.
