The skip-stop along the 1/9 will end in May, meaning that the No. 9 train is headed for that trainyard in the sky...or Queens, as it were (well, it's not really a trainyard...the MTA will get rid of the signs and make new maps). In May, all the stops in upper Manhattan and the Bronx will get No. 1 trains all the time, making some people happy and others, who liked the "local yet express" nature of the 9, will have more time to read. The MTA stresses that the same number of trains will be running, and the seven skip-stop stations "will see more service." It's not a huge change, but Gothamist will miss the number skipping when we'd call the West Side IRT trains the 1/2/3/9.
