How should a DP train be handled when approaching an obvious thermal misalignment if you cannot stop prior to passing over the misaligned track?

How should a DP train be handled when approaching an obvious thermal misalignment if you cannot stop prior to passing over the misaligned track?

• A. Stop The Train Using A Full Service Brake Application
• B. Use A Light Brake Application And Proceed Slowly
• C. Maintain Speed And Monitor
• D. Notify Dispatch And Continue At Reduced Speed

Answer: (A)

When a train encounters obvious thermal misalignment, the priority is to stop the train as quickly as possible to prevent derailment. Using the full service brake applies the maximum deceleration available, allowing the train to come to a halt sooner and before the damaged track section is reached or crossed. Lighter braking won’t provide enough stopping power in time, and continuing at reduced speed or simply monitoring the situation does not address the immediate risk of derailment. Notifying dispatch alone doesn’t mitigate the physical hazard of the misaligned track.
