When moving over diverging routes, what is the maximum speed unless indicated otherwise?

The correct answer is 10 MPH for a train moving over diverging routes unless otherwise indicated. This speed limit is set to enhance safety when trains navigate these complex areas. Diverging routes involve a switch or turnout, which changes the direction of travel, and can pose additional risks compared to straight track segments. By limiting the speed, operators have more time to react to any potential issues, ensuring that the train can safely negotiate the curve and remain on track.

Higher speeds increase the likelihood of derailment or accidents when turning, especially if the track geometry is influenced by factors like track condition, the weight of the train, and environmental conditions. Therefore, adhering to the maximum speed of 10 MPH helps maintain a safe operating environment while transitioning through diverging routes.
