  "textContent": "The safety circuit accommodates engines with similar safety circuits in a potential-free manner, whereby the on-board network voltage (DC) of a first engine passes via its coupling, a relay closing contact (k101) in the second coupled engine and back via the coupling to the loop engagement relay in the first engine. If this circuit fails the safety circuit in the first engine is interrupted, the first relay (K10) lies in the safety circuit or in a loop relay (SBS) circuit and the loop access relay (K9) is connected to the on-board network voltage via a contact (k72) that is opened when the second train is coupled.",
