Amidst the ever expanding urban landscape of Southern California the seemingly timeless sound of a hard working eastbound freight pierces the afternoon air in Redlands, CA on the western slope of famed Beaumont Hill near the timetable location of Bryn Mawr. Behind Union Pacific motors 8445-6878 the eastbound West Colton, CA to El Centro, CA manifest leave the 'cities' behind and prepare to crawl into the serpentine canyon that is the western slope of Beaumont Hill, also commonly referred to as San Timoteo Canyon. In the distant foothills the entrance to another fabled Southern California rail route, Cajon Pass, can be seen. A sharp eye can spot the Cargill elevator in Verdemont, CA.
