I do remember back then during the Late 90's or Early 2000's,North and Southbound trains skipped the Bowery Street Station as a Nassau Street Express between Canal Street and Essex-Delancey Street Stations during Midday hour,while the Midday to 9th Avenue operated as a Local,don't remember if it was ever a GO. I noticed on the maps during that time that the J-M-Z letters on Bowery Station where lighter and the other stations letter J-M-Z were bolder as to indicate Bowery was skipped during those hours.Does anybody remember that service pattern ?
