Green Line

I've been wondering around the city on my unlimited "Charlie Pass" for the Boston T. Except for the smell and lack of sunshine, I love pretty much everything about T trains. The noise of approach, the way they make the ground shake, their varied designs and colors, bright headlights as they zoom towards us to the station and, because I am in no hurry, their red brake lights twinkling as they dip around a dark bend into their tunneled traverse.
