Answer: An Initial Terminal and Road Air Brake Test (Class 1)
Feedback:
A brake system that has not been connected to a continuous source of compressed air of at least 60 psi for 24 hours or more is considered "off air." This requires charging the brake system and performing a Class 1 to verify that all the brakes function correctly on each car.
