The D-Dock system is a tool for inspecting relays and circuits during train operation, monitoring voltage and current without affecting service. It consists of a D-Dock Test Adapter connected to a Break-Out box. The Test Adapter is placed between the existing relay socket and D-relay in the train. All 14 relay pins are wired to the Break-Out box, allowing measuring equipment such as multimeters, scope meters or data analyzers to log operations over longer periods, making fault finding easy. The D-Dock fits tightly packed relay panels and small cabinets and can operate unattended during normal passenger service.
