Below GM50 pulls a mixed freight across a grade crossing.

Below is a pic of the same train from another angle.

On most days GM50 drew assignments like any other locomotive.  Here it is seen as the trailing unit on a mixed freight.

Below GM50 is on the point with a GP38 assisting.  A Chessie 2-bay airslide starts off the long string of freight cars being pulled.
