Signal mechanism with integrated switching for controlled stopping of digital locomotives with highefficiency propulsion. Connections for a two-aspect light signal for the required 3 track sections, for safe stopping of the locomotive. The brake module is switched either via a k 83 Decoder or via a conventional 7272/72720 Control Box. Dimensions 100 x 54 x 22 mm / 3-15/16" x 2-1/8" x 7/8". The brake module requires three insulated track sections in the signal area. The first part is a transition area, which corresponds to the length of a ski-shaped pick-up shoe (app. 70 - 90 mm / 2-3/4" - 3-17/32"). The second section is the actual braking area, in which the locomotive comes to a controlled stop. The length of the braking area is specified by the brake delay setting on the locomotive decoder. This second area should be at least 40 - 50 cm / 15-3/4" - 19-11/16". The third section is a safety section in which the operating voltage is switched off in signal sections, as before. This prevents the locomotive from "slipping through" the signal area unintentionally. The brake module is suitable for light signals and semaphores. Locomotives with built-in digital electronic circuits without a control feature, or Delta electronic circuits sometimes come to a stop in the brake section or even in the safety section. A clear specification is not possible. Consequently, using the 72441 brake module, together with propulsion systems that do not have a control feature, is not recommended.
