If a train is transporting air dump cars, what is its maximum allowed speed limit?

When transporting air dump cars, the established maximum speed limit is 30 mph. This regulation is in place due to the nature of air dump cars and the potential risks associated with their operation. Air dump cars are often used for handling materials that can be sensitive to high speeds, and their design necessitates a lower speed limit to ensure safety and stability during transit.

Maintaining this speed limit helps prevent accidents and ensures that the cargo remains secure throughout the journey. It is crucial for train crews to adhere strictly to these limits to promote overall safety on the rail network, both for the crew operating the train and for other rail and road users.
