INFORMATION 
SHORTEST LINE— FASTEST TIME EAST 
1. The San Diego and Arizona Railway, completed Decem- 
ber 1, 1919, forms in connection with the Southern Pacific and its 
eastern connections, a new transcontinental route between San 
Diego and the East. Through Pullman cars are operated between 
San Diego and Chicago on Golden State L'mited in connection 
with the Southern Pacific and Rock Island Lines, and between 
San Diego and New Orleans on Sunset Limited in connection 
with Southern Pacific. It is the terminal railroad of the shortest 
line between Kansas City and the Pacific Ocean and between 
New Orleans and the Pacific Ocean. 
2. Distance between San Diego and El Centro, 148 miles; 
(Between San Diego and Yuma, 220 miles). 
3. Elevation at Hipass, highest point on line, 3,660 feet; at 
El Centro, lowest point on line, 49 feet below sea level. 
4. Grades: Maximum grade Westbound, 2.2%; Eastbound, 
1.4%. 
* 5. Cost of San Diego and Arizona Railway, $19,000,000. 
and is owned one-half by the J. D. and 
A. B. Spreckels Securities Company, 
and one-half by the Southern Pacific 
Company. 
6. Railroad crosses United States- 
Mexico International Boundary Line at 
Tijuana and Lindero. Boundary at 
Lindero is crossed in Tunnel No. 4, 26 
feet from the west end. Runs 44 miles 
through Mexico, known as Lower Cali- 
fornia. Ten miles is the greatest dis- 
tance into Mexico from the Inter- 
national Boundary line. 
7. There are 21 tunnels on the San 
Diego and Arizona Railway, one partly 
in Mexico and partly in the United 
States. Cost of tunnels, $1,760,200. 
The longest tunnel, No. 14, is 2,597 feet, 
and the shortest tunnel, No. 1, is 187 
feet. The total length of all tunnels is 
2.98 miles. 
When passing through the tunnels, notice that you are not 
bothered with objectionable fumes and smoke from locomotives, 
as is usual when trains are operated through tunnels. This is 
due to the large bore of tunnels, exceptionally light atmosphere, 
and a slight draft continually passing through Carriso Gorge. 
8. Distance through Carriso Gorge is 11 miles, and cost 
for construction, $3,939,000.00. Depth of Gorge from railroad, 
900 feet. 
Carriso Gorge takes its name from the grass in its depths, 
which is used by Indians in basket work. Mountains are southerly 
extension of the Sierra Nevada Range. 
Notice the 22 fan leaf palms and spring at bottom of Gorge 
between Tunnels 20 and 21. 
9. Campo Creek Viaduct, 77 miles from San Diego. Length, 
600 feet. Height, 185 feet. Cost, $115,700.00. 
10. The San Diego and Arizona Railway is the only railroad 
that received permission from the United States Government to 
continue construction during the entire period of the world war 
because of the importance of reaching the port of San Diego, 
where the United States Government maintains an extensive 
Naval Base. 
11. One feature of importance, from the viewpoint of our 
Government, is that the completion of the San Diego and Arizona 
forms, in connection with the Southern Pacific, a railroad direct 
along the Mexican Boundary from the Pacific Coast to the Gulf 
of Mexico. 
12. Tijuana is noted as a Mexican sight-seeing place for 
tourists. The Lower California Jockey Club holds a 100-day or 
longer racing meet at Tijuana once each year, which has a large 
attendance from all over the world. Opening date, Thanksgiving 
Day. 
13. Notice when approaching Redondo westbound or leaving 
Redondo eastbound, the horseshoe curve where the track can be 
seen on the mountain side, three different locations at one time. 
14. Imperial Valley: A desert waste in 1900. Today is an 
agricultural empire of 531,674 acres under irrigation on the 
American side, with more than 200,000 acres on the Mexican side. 
Population, 50,000 in 1923. Shipped in 1923 about 50,000 car- 
loads of products by freight of a value of nearly $50,000,000, 
including 14,000 carloads of cante- 
loupes and melons, 8,000 carloads of 
lettuce and vegetables, 125,000 bales of 
cotton, and 7,000,000 pounds of dairy 
products. The valley is irrigated from 
Colorado River, and is perhaps the 
richest producing farm area in the 
world. 
15. Desert Plant Life: After 
leaving Coyote Wells westbound, and 
continuing up through Carriso Gorge, 
the desert is covered with many species 
of desert plants, including many vari- 
eties of cacti. In the spring of the year 
many of these plants are in full bloom, 
which adds to their beauty. Pictures, 
together with the namos of some of the 
principal plants, are shown on the 
reverse side of this sheet. 
16. Jacumba Hot Springs: Sum- 
mer and winter resort 92 miles from San 
Diego. Altitude, 2,835 feet; hot and cold artesian mineral water; 
large outdoor swimming pool; hotel, tent houses, cottages and 
auditorium. 
17. On the “Golden State Route,” between San Diego and 
Yuma, the Inter-California Railway, a part of the Southern 
Pacific System, is used between Mexicali and Algodones, oper- 
ating a distance of 52 miles through Mexico. 
18. Yuma, on Southern Pacific: Near Yuma is located the 
Laguna Dam for diverting water from the Colorado River for 
irrigating purposes. There are 50,000 acres in Arizona irrigated 
from the Laguna Diversion Dam at this time. Project under way 
to irrigate 6,400 additional acres of Mesa land within the next 
year, and eventually there will be 120,000 acres of land under 
irrigation in the vicinity of Yuma. Climatic conditions provide 
for the growing of some of the most delicious fruits that are grown 
anywhere in the world. 
19. Ask the conductor, brakeman or observation porter for 
time that train crosses the International border and passes points 
of interest. Additional copies of this circular may be had upon 
application to porter.
