While a film student at Cal State Northridge, where its director Sidney Salkow taught courses, I saw this film. It was a 16mm print. The professor, Dr. John Schultheiss (now Chairman of the department) ran the fight scene that takes place in the diner and works its way into the rail yard. I remember Sidney talking about the film and another that he had directed (a "noirish" film that I can't remember the name of). It was definitely memorable. Sidney Salkow worked on Broadway before he started in film but, definitely knew how to move the action along.
Dr. Schultheiss might know whether the film is still available.
