Many years ago I lived in that area and was a regular rider out of 179th Street. I have walked Hillside Avenue all the way to and beyond the city line in my younger days. Often I would walk east on Hillside Avenue and I believe the tracks continue as yard tracks nearly to 188th Street. I suggest if you have time sometime that you do that walk, you will notice the vents in the sidwalk and in areas you can probably still hear the trains underneath although they do not travel at the speeds that they do in revenue service west out of 179th Street. As you may know, 179th Street is a two level yard with the outside tracks using the lower level and this was used by "E" trains in the days that all of them ran to 179th Street while the two inside tracks were for "F" trains which yarded and turned on the upper level. It has been many, many years since I have been in or ridden the subway in that area so I am not sure just how that facility is utilized today although as others have pointed out, it is probably much less than in the past. I do know that the station was one very busy spot in the rush hours.
