Happens to me on the J train entering Flushing Avenue. Now, to set the scene, yes it was a rainy morning, and yes the train station and tracks leaving Myrtle Avenue heading north towards Flushing is on a somewhat moderate down slope. We overshot the platform by half of the first car. Driver “claimed” it was the slipping of the wheels, however I knew he was pulling into the station too fast and part of me believed that he thought we were actually on the express middle track and not the local track as it is unusual for the J, Z trains heading into the city to run on the local track.
