What is the maximum brake cylinder piston travel on E-15 locomotives?

Answer: B — 6 inches

The maximum brake cylinder piston travel on E-15 locomotives is 6 inches. This measurement is crucial for ensuring the proper functioning of the air braking system. The brake cylinder piston travels within a specific range to create the necessary braking force while maintaining control and safety standards. When the piston operates within this 6-inch limit, it ensures sufficient airflow and pressure is regulated accurately, allowing for effective braking performance without risking mechanical failure or reduced stopping power. Understanding this specification is essential for personnel maintaining and operating these locomotives, as it directly impacts the overall braking integrity and reliability.
