This is the BNSF Cajon Sub. In 2007, the last year of filming, work began on a 3rd track across the Pass. We see both BNSF and Union Pacific trains since UP has trackage rights over the Pass. This is a busy line with cargo in and out of Los Angeles and its ports. In the last part of our 4 part series, we cover Westbound traffic between Alray and San Bernardino.

*About this show:* From the great San Bernardino Valley to the high desert community of Barstow lies one of the busiest and most scenic mainlines in the country. At just over 81 miles in length, the BNSF Cajon Sub is a powerful artery that plays an integral role in moving trains to and from Southern California.
With its stiff climb over Cajon Pass, endless flow of traffic, and vistas of stark beauty, the Cajon Sub is a place of limitless photo opportunities for railroad photographers. Over 5 years Pentrex visited the subdivision numerous times, so we'll see the pass in all weather.
This is part 4 of a 4 part series. This video takes a look at Westbound traffic between Alray and San Bernardino.
Across the four parts of this special series, we see over 500 trains!
