Honestly, none of us really know anything. We have no idea when the next class is going to be, how big its going to be, or what list # they're going to get up to. Any estimate is probably going to be inaccurate. MTA human resources told me that they dont even know when the next class will go in. When the MTA needs more track workers, they get a call from some "upstairs" and they are told to start processing more candidates, and no one knows when that will be. All i can say is that as of monday, the first training class is officially over, and that the rep from human resources said historically they have indeed put more than one class in per year.
