In 1882, the SP started building a line from Mojave to Needles to head off the advancing Atlantic & Pacific. This line was completed in 1883. The main objective was to keep competitors out of California. Through some horse trading the line to Needles became part of the Santa Fe and lines south of the Arizona Territory into Mexico became part of the Southern Pacific.
The first installation of automatic block signals on the ATSF Coast Lines was a 2 mile stretch at the north end of Needles in 1907. These were the lower quadrant semaphore signals. ATSF completed installation of automatic block signals between Barstow, CA and southwest to Cottonwood in May 1911 and from Barstow east to Daggett in December 1911. ATSF installed an 18 lever GRS interlocking machine at Daggett. Cottonwood had a temporary interlocking plant installed in an old refrigerator car. When double track was extended toward San Bernardino the car was moved to the new end of double track. The railroad completed installation of automatic block signals between Needles and Goffs in October 1912. The installation of automatic block signals from Needles, CA to Topock, AZ was completed in May 1913. During 1918 it was installing signals between Goffs and Daggett. It completed the installation of automatic block signals between Daggett and Bagdad on double track (69 miles) in 1918 and completed the installation of automatic block signals between Goffs and Bagdad on double track (61 miles) in 1919. I think all of these signals were upper quadrant semaphore signals.
The single track line from Barstow to Mojave received signals during the early 20s. The signals were converted from semaphore to searchlight signals when the line had CTC installed around 1959.
The line from Needles up to Ibis received CTC in 1999. This was extended to Goffs in 2000 and west to Daggett in 2001. All of my photographs in this series are on disks 49 and 50. I have also added pictures taken by Jack Delano in 1943 and my brother Steve during the 70s. One page will have a link to the Santa Fe Hot 27.
For those modeling the Santa Fe in the late 60s, the library contains a series of pages with detailed freight train consists. The trains featured on those pages were observed at Winslow and Barstow. As reference, I've added timetables from the Needles and Mojave Subdivisions.
