The present invention concerns a safety contact for a safety line in a train, the safety contact comprising a controller and a safety switch circuit, wherein the controller comprises a sensor input for receiving signals indicating failure, wherein the safety contact comprises an input for a safety line input signal, which input is operably connected to the controller, whereby the controller is configured to receive a control signal representing a safety line state which is dependent on the safety line input signal received at the input, wherein the safety switch circuit comprises a set of at least one safety switch, the safety switch being positioned between a power supply and an output, wherein the controller is configured to: upon receiving a control signal indicating a working safety line state and a sensor input value representing no safety function failure, close said safety switch of the safety line circuit, thereby putting an output signal on the output, the output signal indicating a working safety line state, and upon receiving a control signal indicating a non-working safety line state or a sensor input value representing a safety function failure, open said safety switch of the safety line circuit, thereby essentially interrupting the safety line.
