One of North America's most exciting train watching locations, California's Cajon Pass funnels BNSF and Union Pacific heavy freights through the San Bernadino Mountains. You'll visit hot spots such as Blue Cut, Sullivan's Curve, and Hill 57 to see C44-9Ws, ES44s, SD70Aces, and other large, modern motive power straining hard to drag manifests and unit trains up the triple-track grades - and giving the dynamic brakes a workout on the downgrades!
