The GP's linked article[0] doesn't say anything about fonts. It says that the MTA sued someone for using the letter 'N' in a circle on a T-shirt. Not even the same color scheme. Judging from the examples on one of the MTA's branding pages[1], there doesn't seem to be anything particularly unique about the font they're using. They don't even mention it by name. Other sources claim the official signage is a mix of Helvetica and Akzidenz Grotesk. In any case, fontface designs are not copyrightable in the US. Fonts can be (as programs/data) but that isn't really relevant here.
