The Problem With ECP Systems in the Wild

An ECP system would be capable of like a partial release. The problem was that when they tried it on actual trains in the wild,. in the wild, none of it worked. They just like they like each other too much. It's like an interference issue early. There was one instance in Australia, which is so far the only place that commonly uses ECP on freight trains but only on certain iron ore trains in Australia. And then when the engineer went back to set hand brakes while the problem was resolved, the ECP system released the brakes and went merrily on its way without any one in it.
