While southern California's Metrolink cycles their locomotives out for installation of Positive Train Control (PTC) equipment, the agency has leased three former GO Transit F59PH diesels. Shoving on the rear of Metrolink train 689 (Irvine to Los Angeles) is Rosen Beaudin Group 18520 (ex-GOT 520), still in GO colors. Combined with coach 198, wrapped to promote Metrolink's weekend service, this has become a very colorful train! (Fullerton, California; September 17th, 2013)
