ECP overlay system for W-type triple valve

An ECP overlay system, comprising:

• a manifold body comprising a pipe bracket face configured to engage a face of a pipe bracket of a vehicle brake system, a valve face configured to engage a face of a W-type triple valve of a vehicle brake system, and an electric manifold face;
• an electric manifold assembly engaged with the electric manifold face of the manifold body, the electric manifold assembly having a pneumatic mode where the electric manifold assembly is configured to allow pneumatic-only control of a brake cylinder of a vehicle brake system and an ECP mode where the electric manifold assembly is configured to allow electronic control of a brake cylinder of a vehicle brake system,
• wherein the manifold body further comprises a plurality of ports defined by the pipe bracket face, a plurality of ports defined by the valve face, and a plurality of ports defined by the electric manifold face, the plurality of ports of the pipe bracket face are in fluid communication with the plurality of ports of the valve face via a plurality of passages extending through the manifold body, the plurality of ports of the electric manifold face are in fluid communication with the plurality of passages,
• wherein the plurality of ports of the pipe bracket face and the plurality of ports of the valve face each comprise an auxiliary reservoir pressure port, an accelerated release reservoir pressure port, a brake pipe pressure port, a brake cylinder pressure port, and a brake cylinder pressure exhaust port, the auxiliary reservoir pressure ports of the pipe bracket face and the valve face are in fluid communication via an auxiliary reservoir pressure passage, the accelerated release reservoir pressure ports of the pipe bracket face and the valve face are in fluid communication via an accelerated release reservoir pressure passage, the brake pipe pressure ports of the pipe bracket face and the valve face are in fluid communication via a brake pipe pressure passage, the brake cylinder pressure ports of the pipe bracket face and the valve face are in fluid communication via a brake cylinder pressure passage, the brake cylinder exhaust ports of the pipe bracket face and the valve face are in fluid communication via a brake cylinder exhaust passage.
