When the Load Dispatcher determines a reduction in power is necessary, how will Electric Trains Operate?

• A. High Speed Trainset (HST) Power Car and ACS-64 effort must not exceed 50,000 foot pounds, ALP 44 and 46, effort must not exceed 1,500 AMPS, MU cars P-2 position.
• B. HST and ACS-64 power restrictions are not specified for this scenario.
• C. Only the ALP 44 and 46 are restricted, other units unrestricted.
• D. The restrictions apply to all locomotives equally regardless of type.

Answer: (A)

When a power reduction is required, the traction limits are specific to the type of locomotive so each unit contributes safely to the overall reduction. The High Speed Trainset power car and the ACS-64 are limited to a maximum tractive effort of 50,000 foot-pounds, while ALP-44 and ALP-46 units are limited to drawing no more than 1,500 amps. In addition, the MU cars must be set to the P-2 position to enforce these reduced-power conditions across the train. This combination ensures the train slows in a controlled, safe manner without overstressing different traction systems. Other options either ignore these type-specific limits, omit the P-2 setting, or incorrectly apply the same restriction to all units, which would not reflect how the system manages diverse locomotives during a power reduction.
