While rounding a sharp curve in a yard, what is the recommended speed for a train?

When rounding a sharp curve in a yard, the recommended speed of 10 MPH is considered safe and effective for the stability of the train and the safety of the personnel involved. This speed allows for sufficient control and responsiveness to any required adjustments in the operation while minimizing the risk of derailment or excessive wear on the tracks and train equipment.

Maintaining a moderate speed like 10 MPH on sharp curves helps ensure that the forces acting on the train, such as centripetal force, are within acceptable limits. It also gives the operator better visibility and reaction time to navigate any unexpected obstacles or changes in the yard environment.

Higher speeds could compromise safety and operational integrity by increasing the likelihood of derailments or equipment failures, while significantly lower speeds may not be practical in terms of efficiency and operational flow within the yard.
