What is the system maximum allowable EPA at the rear of an Intermodal Equipment only train?

• A. 24
• B. 26
• C. 28
• D. 30

Answer: (C)

The key idea here is how much end power the rear of an Intermodal Equipment only train is allowed to use while maintaining safe handling. In these trains there isn’t a locomotive at the back to help control motion, so the system sets a strict cap on what can be considered available power at the rear. The value 28 is chosen because it provides enough control for move/stop actions and braking response without exposing the couplers, cars, and track to excessive dynamic forces or slack action that could cause stability problems or equipment damage. Values lower than this would limit maneuverability and braking performance, while higher values could compromise safety in typical intermodal operations.
