Frost Flyover
The fastest speed ever recorded through the Cajon Pass was 100 miles an hour (1905) down this stretch from Summit to the Frost Flyover. Some of our operators have attempted to beat this record with their trains.

Flying at a scale 75 mph, the A-B-A configuration of EMD F-7's pull the Santa Fe's flagship, the Super Chief, under the flyover.
The Santa Fe and Union Pacific ran helpers all the way to Victorville on the 1.5 per cent downhill grade (again, to slow the train down.) The alignment of tracks coming out of Cajon, however, made opposing trains pass each other on the right (left-hand running).

The California Local passes over the eastbound Super Chief.

The Santa Fe, as is the manner of most railroads in the United States, was a right-hand running railroad, with trains passing on the left. Since the engineer's seat was on the right, while the fireman, who fed the engine with oil was on the left, signal masts (for the engineer or conductor) were placed on the right. They would not be seen, if a train was passing on the right, so alignment of the tracks was an important safety issue.

To return the trains to passing one another on the left required one track to pass over the other in an engineering structure called a flyover.

As the trains pass, the Joshua Trees are the only spectators.
