What is the maximum speed allowed in any yard unless otherwise posted?

The maximum speed allowed in any yard, unless otherwise posted, is commonly set at 10 MPH. This speed limit is established primarily to ensure the safety of workers and equipment within the confines of the yard, where activities such as loading, unloading, and maintenance take place. At this reduced speed, train operators can maintain a higher level of control and respond quickly to any unexpected situations that may arise, such as pedestrians or vehicles crossing their path.

Higher speed limits, such as 15 MPH or 20 MPH, would increase the risk of accidents in these busy areas where many operations are occurring simultaneously. Conversely, a limit lower than 10 MPH, like 5 MPH, may not be practical for all operations within the yard. Therefore, the standardized 10 MPH reflects a balance between operational efficiency and safety.
