(Patrick Bateman @ May 05 2005,18:09) It's much, much cleaner, 81% versus 14%. http://ny1news.com/ny1/content/index...id=5&aid=50254 That's a BIG difference in my book. Wow, I always thought that the A and C trains were pretty dirty. Â I only ride the 1 and 9 every now and then when the A and C are down so I haven't really noticed them that much, but that must mean that they are friggin DIRTY. It has to do with the fact that the 1-9 can be only be cleaned at one end of the subway line (Van Cortlandt Park) due to the circular configuration of the South Ferry station. As evidence, compare 1-9 to the 2-3 (especially the 2 instead of the 3, since the 2 has the newer cars). The 2-3 is usually much better--not perfect, but acceptable most of the time.
