One of the biggest drifts on the Jackson Line is Alden Hill. The crew this day was struggling to wing back the drift here. Out of the blue, the ditcher crew said told the engineer to back up a half mile. Leopard and I repositioned not knowing what was going on? Next thing we hear is, "ahead 40." Yeah what a experience! Glad the next snow storm was coming in to add some color to an all white shot. To this day I am not sure why the fly by in the middle of the winging job???
