An ECP overlay system for a UIC-type distributor valve includes a manifold body having a pipe bracket face configured to engage a face of a pipe bracket of a brake system, a valve face configured to engage a face of a UIC-type distributor valve of a brake system, and an electric manifold face. The system further including an electric manifold assembly engaged with the electric manifold face of the manifold body, with 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 brake system and an ECP mode where the electric manifold assembly is configured to allow electronic control of a brake cylinder of a rbrake system.
