From 18th St, our journey takes a turn northwest up to the Upper West Side. Here, still on the original IRT Subway line, lies the 91st St station. In service from the original opening of the IRT in 1904, the 91st St station was a local station on the IRT Broadway line until it was removed from service in 1959. Like 18th St and Worth St, 91st St was closed after the systemwide platform lengthening project, as it comes within close proximity of the full length 86th St and 96th St platforms (especially 96th, which ends close to 93rd St). Today, the 91st St station sits collecting dust, with most of the original tile work under several coats of spray paint.
