Abstract
A brake system for rail cars is disclosed. The brake system includes a first source for providing a braking force to a first and a second braking apparatus, a second source for providing a separate force to the first and a second braking apparatus, and a manifold for simultaneously delivering a braking force from either the first source or the second source to the first and second braking apparatus. The manifold includes a positionable valve operable under the influence of pressure differentials applied thereto by the first source and the second source and wherein the position of the valve controls which braking force will be applied to the first and second braking apparatus. The brake system further includes a controller arranged in operable combination with the first source and the second source for inhibiting a braking force from the second source being directed to the first and the second force to the first and the second braking apparatus.
