The stopping section is passable in the opposite direction, just like with the federal railway. For example, the train slows down when approaching a stop signal (contact open). The journey continues automatically after the signal indicates "clear" with a slow acceleration up to the speed set at the signal control panel. The built-in current limitation restricts the current to 2 A. The electronics do not require a separate operating voltage. The module is pre-assembled and tested for connection readiness.
