What is the maximum allowed speed for light engines operating long hood forward in adverse conditions?

The maximum allowed speed for light engines operating long hood forward in adverse conditions is 45 MPH. This speed limit is established to ensure the safety of operations, as adverse conditions can include factors such as inclement weather, poor track conditions, and reduced visibility.

Operating at a speed of 45 MPH allows for a reasonable balance between maintaining operational efficiency and ensuring safety. Higher speeds could increase the risk of accidents due to decreased stopping distance and reduced control over the train in potentially hazardous situations.

Conversely, the other speed limits are set lower than this maximum to account for specific scenarios that might compromise safety, thus the choice of 45 MPH as the maximum in adverse conditions allows for both flexibility in operations and a cautious approach to safety management. Both regulation compliance and practical safety measures dictate that this speed is appropriate for light engines in less than optimal conditions.
