The Dwarvin N Scale Turnout Signals Kit for Stall Motor Switch Machines is designed to integrate with stall motor switch machines, most notably the Tortoise, Walthers (depending on use of the auxiliary control), Rapido Railcrew, Cobalt and similar switch machines, without soldering wires, to provide signals to the oncoming locomotives. System components include three signals with 2 pairs of 2' of 0.75mm fiber each, one N Signal Controller unit and two suitcase-style Quick Splice Connectors. The system can be purchased with or without signals and the controller is also available separately.
