Tehachapi - the name conjures up images of The Loop wherever railfans and modelers gather throughout the world. But railroading in Tehachapi is much more than just the loop alone. It involves the entire 70 miles of railroad between Bakersfield and Mojave. Building a replica of this line has challenged modelers just as the pass itself challenged the railroad barons of a century ago.
The La Mesa Model Railroad Club has responded to this challenge by building an HO scale (1/87th actual size) model of this joint Southern Pacific - Santa Fe line with nearly curve-for-curve and switch-for-switch accuracy. This single track railroad, built through a notch in the Tehachapi Mountains, carries nearly all north-south rail traffic between central and southern California. It is also the eastern outlet for most of the produce grown in the San Joaquin Valley.
Two of the most attractive things about the Tehachapi are the mountain scenery and the nearly continuous series of sharp reverse curves forced upon the railroad by the rugged terrain. The famous Loop is located at Walong siding, where an engine of a 100 car train spirals up to cross directly over its caboose 70 feet below. In several places the line doubles back upon itself, making it an ideal candidate for modeling. The model is unique not only for its size but for its geographic fidelity. Literally thousands of photographs of the prototype have been used to ensure that each detail closely models the features of the actual area. The La Mesa Model Railroad Club meets every Tuesday at 7:00 pm and Monday work session are from 10am-6pm.

Went out to Fountain Hills today and "due to rain" I shot from the cheap seats, after a few attempts I hit road back to Scottsdale.
Upon exiting the freeway near home, I looked out over the cotton field during that golden hour sunset and decided to make a U-turn and stop to take a few shots.
Whats that saying? "never set out for a shot because you wont get it and will probably find unplanned gold elsewhere"... :)

This is the surviving test road loop near Ottawa, Il. There were six loops at the test site when constructed in 1956-58. The loops were approximately one mile in distance. One leg concrete the other asphalt. This photo is looking West from the East end of the loop. I-80 is to the far right. The other five test loops were situated where I-80 runs today. This particular loop was used for testing the effects of weather on the pavement.
(NOTE: I took this shot with my digital camera mounted to the top of a 12 foot pole. I set the timer and positioned the camera with about 4 seconds to go. I also shot some video using this technique but, my aim was off and not as good as the stills.)

This was too long to fit into my frame, so it had to be diagonal, and a tad looped! I'm not sure which Geometrid this is.

In the 1870's the Southern Pacific (Central Pacific) Railroad sought to link their rails in central California to those in Southern California. The path was blocked by the rugged Tehachapi Mountain range, which acts as an east-west barrier between Bakersfield and Los Angeles. Since construction directly south was impractical, the Southern Pacific Railroad decided to go southeast to Mojave, through the Tehachapi Pass. The summit at Tehachapi Pass was 4000'. Construction from Bakersfield to Caliente was somewhat routine, but from that point on the elevation going east rises quickly. From Caliente to the summit (now the City of Tehachapi) the rise is 2,735 feet. The maximum grade permitted was 2.2%. By routing the track alongside the slopes of the Tehachapi foothills, engineer William Hood could envision completing the task. However, just east of Keene, there was an apparently unsolvable problem. An increase in elevation of nearly 80 feet was required, unattainable using typical designs .
The problem was solved by constructing a unique loop. Going southeasterly from Keene, a train first passes through an entry tunnel. The track then does a complete counterclockwise loop, passing over the entry tunnel before continuing easterly. (See sketch below). The loop is sized to have a length adequate to achieve the needed gain in elevation. The result is a loop 3,799' long, with a typical diameter of about 1210 feet. By continuing to gain elevation throughout the loop, engineer Hood was able to make up the needed elevation (about 77' rise in the loop). With modern freight trains, often more than a mile long, the locomotive passes over (or under, depending upon direction) the final cars of its own train!
The entire track from Bakersfield to the summit was completed July 10, 1876. In all, in addition to the loop, there are 18 tunnels with a total length of 8,240'. There are 8,300
