Back in the 1920s, the New York Central Railroad had a line at street level on the lower west side of Manhattan. The area was industrial back then. The rail line was dangerous on the crowded streets so the company built an elevated trestle, the High Line. The service eventually fell into disuse. In the last few years it was transformed into a brilliant park space. The views of the city and Hudson River are stunning; the gardens are a delight. Some of the most interesting views are just off to the sides. These are a few samples.
