For push-pull trains that make a stop after passing a distant signal, what speed must they not exceed when approaching the home signal?

• A. 20 MPH
• B. 30 MPH
• C. 40 MPH
• D. 50 MPH

Answer: (C)

When approaching the home signal for push-pull trains that have passed a distant signal, it is important to understand the specific restrictions placed on these trains for safety reasons. The correct maximum speed of 40 MPH is established to ensure the crew has ample time to react to signal indications and to maintain safe stopping distances. This speed limit helps mitigate the risk of violations of signal indications and decreases the likelihood of accidents, especially when trains are preparing to stop. The regulations are designed with the understanding that a push-pull train, which may have a different braking response and handling characteristics compared to conventional trains, needs a lower speed limit than what might usually be allowed under other circumstances. Therefore, the specified limitation of 40 MPH provides a balance between operational efficiency and ensuring the safety of the train operation. Understanding this context is crucial in recognizing how maximum speed regulations help maintain safe train operations within the framework of signal management and train control.
