Cajon Pass refers to an area between Devore and Hesperia, CA, where the Union Pacific and BNSF lines climb from the Los Angeles Basin to Victor Valley and the Mojave plateau. Devore, at the southern end, is about 60 miles from Los Angeles, and it’s about 24 miles from there to Hesperia.
Cajon is a real railfan's mecca, and the year round California waether means you'll almost always find chasers around. Some go to great lengths to get that perfect shot, and there are consequently tons of sites on the web showing photographs of Cajon, many the result of years of visiting by enthusiasts.
BNSF and the Union Pacific share trackage rights, so you’ll see trains hauled by either carrier on the different lines. Once in a while, you may even see a mixed engine consist.
I visited in September 2008 and February 2010. The photos on this page are from both visits.
A Union Pacific mixed freight climbs up Cajon Creek Wash out of Devore on what is known as the North Track and passes an eastbound BNSF intermodal freight descending on the South Track beneath Ruddell Hill.
These photographs were taken from the south end of Cajon Boulevard.

A little further north, the train is about to enter Sullivan’s Curve, the west spur of the BNSF line.
The head end of the train can be seen just left of centre of the top view. In the bottom view, it is just visible on the very far right.
These two photographs were taken from Cajon Boulevard near Cajon Junction.

The California Southern Railroad, a subsidiary of the ATSF, built the first railway through Cajon Pass in the 1880s to connect Barstow and San Diego, CA. The line was completed in 1885 with a ruling grade of 3%. It is known as the South Track and is the lower track in the views above.
UP GE AC4400CW #5670 and UP C44AC #6589 are on the rear end.
In 1905, the Los Angeles and Salt Lake Railroad began operating over the pass on ATSF rails via a trackage rights agreement.

In 1912, work started on a second track north of the original ATSF alignment. The ruling grade of the new track, which was known as the North Track, was 2.2%,.
Although two miles longer, the new track was used for eastbound, uphill trains, while
downhill trains headed west on the original route. This meant trains had to run “left-

In 1921, the Union Pacific gained a controlling interest in the Los Angeles & Salt Lake. The LASL trackage rights were transferred to the UP, which gained access through Cajon Pass, and the agreement is still in effect.

In 2007-
In 1996, the Union Pacific merged with Southern Pacific. The Palmdale Cutoff was then rolled into the Union Pacific and ATSF trackage agreement. Currently, both the Union Pacific and BNSF have joint trackage rights throughout the Pass.

In 1996, Burlington Northern and AT&SF merged to form the Burlington Northern Santa Fe Railway (BNSF). The railroad has over 33,000 route miles in 28 U.S. states, as well as two Canadian provinces. The Union Pacific has over 38,000 route miles in 23 U.S. states.
