One of the newest stations on the red line, near the Charles River, in Boston. The red line is a true metro, with wide cars, third rail, underground in the city but on a grade-separated right of way in the ‘burbs and on bridges.
Stairs were poured concrete, but with rubber pads making the climb much easier on the feet. Escalators were provided only for the up direction.
Ottawa plans a sterile zone along its LRT tracks. Draw a line 45 degrees up from the rail, remove all vegetation, so nothing can fall on the track. Boston showed a more tolerant attitude. At this station, there were lots of trees — probably self seeded — very close to the train and the rail. Pleasant.
