What happens to locomotives if the ambient temperature is 40 degrees or above and they are not needed?

When locomotives are not needed and the ambient temperature rises to 40 degrees or above, shutting them down is advisable for several reasons. High ambient temperatures can lead to increased wear on the locomotive systems if they remain idling for extended periods, as excessive heat can exacerbate issues in the engine and cooling systems.

Shutting down locomotives also helps conserve fuel, reduce emissions, and minimize operational costs. Additionally, the engines may require cooling to prevent overheating, and allowing them to cool down when they aren’t in use is beneficial for maintaining their longevity and operational efficiency.

While keeping them idle could seem acceptable, it doesn’t align with best practices for locomotive maintenance and management in high-temperature situations. This ensures the equipment is maintained in optimal condition and ready for use when necessary without unnecessary strain on the systems.
