Southern Pacific F-70 Class Flat Car Air Brake System Diagram
The Southern Pacific F-70 class flat car was a 70-foot (21.3 m) flat car built by American Car and Foundry (ACF) in 1952. The car was designed to carry heavy loads, such as transformers and generators. The car was equipped with a Westinghouse air brake system.
## Air Brake System Diagram
The air brake system on the Southern Pacific F-70 class flat car is shown in the diagram below.

The main components of the air brake system are:
* Air compressor
* Air reservoir
* Brake valve
* Brake cylinder
* Brake shoes
The air compressor is driven by the car’s engine. The compressor pumps air into the air reservoir. The air reservoir stores the compressed air. The brake valve is used to control the flow of compressed air to the brake cylinder. The brake cylinder is connected to the brake shoes. When the brake valve is applied, the compressed air in the reservoir is released into the brake cylinder. The brake cylinder pushes the brake shoes against the wheels, which slows down the car.
## Operation of the Air Brake System
The air brake system on the Southern Pacific F-70 class flat car is operated by the engineer in the locomotive. When the engineer applies the brakes, the air compressor is turned on and the air reservoir is filled with compressed air. The brake valve is then opened, which allows the compressed air to flow into the brake cylinder. The brake cylinder pushes the brake shoes against the wheels, which slows down the car.
The air brake system on the Southern Pacific F-70 class flat car is a reliable and effective system for slowing down and stopping the car. The system is easy to operate and maintain.
## Troubleshooting the Air Brake System
If the air brake system on the Southern Pacific F-70 class flat car is not working properly, there are a few things that can be checked.
* Check the air compressor to make sure that it is running.
* Check the air reservoir to make sure that it is full of compressed air.
* Check the brake valve to make sure that it is open.
* Check the brake cylinder to make sure that it is connected to the brake shoes.
If any of these components are not working properly, the air brake system will not work properly.
## Conclusion
The air brake system on the Southern Pacific F-70 class flat car is a reliable and effective system for slowing down and stopping the car. The system is easy to operate and maintain. If the air brake system is not working properly, there are a few things that can be checked to troubleshoot the problem.
