LGB 55081 MTS Reversing Loop Module

Make MTS layout reversing loops simple. No more complex wiring and switches. This clever device detects the short circuit created by a train entering or leaving the reversing loop and automatically reverses the polarity within the loop. Just connect two cables: one to the rails outside the loop and one to the rails inside the loop. Use one module for each reversing loop on your layout. Hint: Not for use on analog layouts. This product is not weather-resistant and should be protected from direct exposure to moisture. For example, you can fit it in a model building on your layout. 80 x 70 x 20 mm
