A hot wheel protection valve includes a body defining a piston passageway and at least one piston positioned within the piston passageway, a first biasing member positioned on a first end of the at least one piston and biased towards a second end of the at least one piston, a brake pipe in fluid communication with the second end of the at least one piston, a brake cylinder in fluid communication with the second end of the at least one piston, and an exhaust port defined in the body and positioned between first and second ends of the valve. Pressurized fluid may be vented from the brake cylinder via the exhaust port upon a combination of brake cylinder pressure and brake pipe pressure exceeding a force exerted by the first biasing member.
