What is the maximum independent brake cylinder pressure allowed on a locomotive equipped with clasp-type brake shoe rigging?

The maximum independent brake cylinder pressure allowed on a locomotive equipped with clasp-type brake shoe rigging is 45 psi. This standard is established to ensure that the braking system functions safely and effectively. Clasp-type brake shoes require a specific pressure to effectively engage with the wheel, providing adequate stopping power while reducing the risk of wheel slippage or damage.

Using a pressure above the prescribed limit could lead to excessive force on the braking components, potentially causing wear or failure of the brake rigging or wheels. This regulation is in place to help maintain the integrity of the braking system and enhance the safety of train operations. Understanding the correct pressure limits is crucial for train crews to ensure they can operate the locomotive safely under varying conditions.
