How much must freight trains reduce their speed when a Heat Warning is issued?

• A. 5 MPH.
• B. 10 MPH.
• C. 15 MPH.
• D. 20 MPH.

Answer: (B)

When a Heat Warning is issued, freight trains are required to reduce their speed by 10 MPH. This is a crucial safety measure to account for the effects of high temperatures on the rails and to prevent potential heat-related track issues, such as buckling. High temperatures can lead to thermal expansion of the rail materials, which can compromise their structural integrity. By reducing speed, the risk of derailment or other hazardous situations is diminished, ensuring the safety of the train, crew, and surrounding communities. The requirement to reduce speed by this specific margin is part of safety protocols established to mitigate risks associated with extreme weather conditions.
