Relays

Relays are necessary to operate loops on the model railway. Therefore, only the block sections OCIC_LN_2 and ICOC_LN_2 are equipped with relays. Before a train is allowed to enter one of these block sections, the relay must be switched to the state Go-In. Then, the train may enter the block section with its original operation direction. After the train's engine has arrived entirely within the block section, the relay must be switched to the state Go-Out, and, coincidentally, the train's operation direction must be switched as well. Without any visible effect, the train now continues to run, but its internal operation direction has changed.
