Southern Pacific F-70 Class Flat Car Brake System Diagram
Introduction
The Southern Pacific F-70 class flat car was a type of railroad car used to transport freight. It was built by the American Car and Foundry Company in 1952 and was used by the Southern Pacific Railroad. The F-70 class flat car had a steel underframe and a wooden deck. It was equipped with two four-wheel trucks and had a capacity of 70 tons.
The F-70 class flat car was used to transport a variety of freight, including lumber, steel, and automobiles. It was also used to transport military equipment during World War II. The F-70 class flat car was a versatile and reliable car that helped to meet the transportation needs of the Southern Pacific Railroad.
Brake System
The F-70 class flat car was equipped with a Westinghouse ABD brake system. The ABD brake system was a type of air brake that used compressed air to apply the brakes. The ABD brake system was a reliable and effective system that helped to keep the F-70 class flat car safe.
The ABD brake system consisted of the following components:
* An air compressor
* An air reservoir
* A brake valve
* A brake cylinder
* Brake shoes
The air compressor was used to compress air and store it in the air reservoir. The brake valve was used to control the flow of air from the air reservoir to the brake cylinder. The brake cylinder was used to apply the brake shoes to the wheels.
When the brake valve was applied, the air from the air reservoir was directed to the brake cylinder. The air pressure in the brake cylinder forced the brake shoes against the wheels, which slowed down the car.
The ABD brake system was a fail-safe system. If the air pressure in the brake system dropped below a certain level, the brakes would automatically be applied. This helped to ensure that the F-70 class flat car could be stopped safely in the event of an emergency.
