As it turns out, I had left out about 10 miles (16.1 kilometers) of routes covered by the Long Island Rail Road in my calculations of the total length of the New York City region’s rail network. It appears that the total route miles are 1,379.9 (2,220.7 kilometers). I’ll soon update the original blog post to reflect the more accurate number. And stay tuned for an explanation of how I came up with the aggregate number in the first place.
(Number still subject to change if I get more info, or realize I made another mistake.)
