Sullivans Curve
 
The original alignment of Santa Fe's trackage to Victorville is the steeper westbound trackage on the right, which was laid out at 3 percent.

A newer alignment was built in 1913 at 2.2 percent grade and was two miles longer than the old alignment.

The path of the new track required a curve. The curve became named for photographer Herb Sullivan, who shot many photographs of Cajon Pass, before and after World War II.

If we were on a real train on the westbound track (the descending track on the right), depending upon our brake type and our tonnage, we would be limited to a top speed of 15-30 mph.

Our trackage is built to those same grades as the prototype. On the real tracks, trains can be out of sight of each other, but ours are only for an instant.

Our modeled Mormon Rocks are visible in this shot. As a comparison, a picture of the rocks is available at: https://en.wikipedia.org/wiki/Cajon_Pass#/media/File:Mormon_Rocks-1.JPG

The Mormon Rocks were so-named after Mormon settlers who came through the pass in 1851 on their way from Utah.

The helper wye at Summit is in the foreground. A cattle pen is here for any passing stock trains. They must stop every 24 hours to water and feed the cattle.

A link to how livestock were handled on the ATSF, with a further link to Union Pacific practices, is at:

Passenger trains on the prototype traveling to the rightmost point of this picture from San Bernardino would have taken 55-79 minutes to go 25 miles. Westbound trains covered the distance 10 minutes faster.
