The Atchison, Topeka & Santa Fe Railway's Cajon Pass was a vital link to the railroad's connection with Los Angeles and remains an important artery of successor BNSF Railway's enormous system in the west. The pass's second line once contained two tunnels but today they have been "daylighted" with large cuts. The railroad line across the pass itself was built in the 1880s but despite the updates it has received over the years and additional tracks built it remains a very difficult route to navigate and one of the steepest main lines in the country, which is a primary reason it draws so many railfans and visitors each year (along with its close proximity to the big cities).
The Atchison, Topeka and Santa Fe Railway, distinctively known as the Santa Fe, likely is not only this country's but also the world's most recognized and famous railroad. It has had its own movie, song, and numerous model trains and other purchasable gifts created in its honor. The railroad's renowned Warbonnet livery has been made in several variations ranging from the more popular silver and red with yellow trim to the blue and yellow. The Atchison, Topeka and Santa Fe Railway, albeit no longer an operating company, is truly a railroad whose name is as common as that of Coca Cola or General Electric.
Cajon Pass is located just northwest of San Bernardino, California and less than 65 miles from downtown Los Angeles. The pass is the result of the San Andreas Fault, which splits two mountain ranges, the San Bernardino Mountains and San Gabriel Mountains. By the 1870s the Santa Fe was looking to expand westward and into California, which it had reached at Nettles in 1883. Through ownership of the California Southern Railroad the AT&SF sought Los Angeles, although to do so meant crossing the rugged mountains which lay to the east of the city.
The California Southern was organized in July, 1880 to begin building north from just south of San Diego and eventually connecting to Barstow. While the railroad never reached Los Angeles, it was able to breach the San Bernardino Mountains and San Gabriel Mountains at Cajon Pass, determined to be the lowest available grade in the region (in actuality the route had already been surveyed earlier by the Los Angeles & Independence Railroad). Work to build the route over Cajon Pass was overseen by Jacob Nash Victor who was general manager of the California Southern. To conquer the steep grades Victor, who was also an engineer, used long, sweeping curves and deep cuts to complete the original route.
Near the summit of Cajon Pass is a long, horseshoe-like curve which featured a tortuous near-3% grade (quite steep for a main line railroad), and was over 2% on both sides of the mountain sloop. The original route opened for rail traffic on November 9, 1885 and in 1913 to help accommodate growing traffic levels a second line was built over the pass, which originally featured two tunnels. However, over the years to help somewhat alleviate maintenance costs both of Cajon Pass's tunnels were "daylighted," meaning they were dug out into deep cuts. This second line is not as steep featuring only a 2.2% maximum grade but the original line, now known as the westbound track, remains a real challenge with its 3% grade.
In 1967 the AT&SF received competition over Cajon Pass when the Southern Pacific completed its Palmdale Cutoff through the area, which sits a bit to the east and is somewhat steeper. However, it remains in use by owner Union Pacific. Also, today, owner BNSF has constructed a third track along the original AT&SF grade to further help keep up with growing traffic demands.
Because of the route's steep grades it has been the scene of many runaways, the most famous of which occurred in May, 1989 when a Southern Pacific freight train lost control and hit a residential area of San Bernardino, killing two civilians as well as the engineer and conductor. Today, with the breathtaking scenery, numerous daily trains, and tough work required to move freight over the pass it is a big attraction for those who like to watch and film trains (aka, "railfans"). The pass has also been featured in a number of books, videos, and magazines over the years.

Authored by Alice Hall the book gives an excellent pictorial history of the pass and its railroad operations covering 128 pages. Also, for more reading on the Santa Fe you might want to consider Santa Fe Railway from Steve Glischinski. Of course, being that the Santa Fe is our country's most legendary railroad hundreds of publications (many quite good) have been written about it over the years detailing various subjects. However, this book will at least give you a general overview and history of the Santa Fe (filled with many, excellent, historical and colorful photographs) at which point you can decide if you are interested in further books of study on the railroad. Even if you are a historian of the ATSF and have not seen this book I'm sure you will enjoy it!
