Therefore, the track has to be gapped on both sides of ll200 reversing loop. Two wires connect into the track in the loop and two wires go to the main line, before the gaps. In any case, the train has to be stopped while traversing the loop.

Lenz GmbH LK Automatic Reverse Loop Module for NMRA DCC

Basic Reversing Loop The only way to prevent this short circuit is l,200 insulate both sides of the track. The LK works according to the fault current principle, with track polarity reversal occurring at mA fault current. A single two-rail gap is not enough, since a passing engine will short the rail through the electrical pick-up on both sides of the gap.


Changing the polarity in the reversing loop will change the direction of the train, since it is dependent on the polarity. While the train is in the loop, the polarity is changed, so that there is no short circuit at the exit of the loop. Usually, the polarity is selected such that there is no short circuit upon entry into the loop.

One still has to ensure that the rails are not short circuited upon entry or exit of the reverse loop. Click an image to enlarge. All other marks are own by their respective owners. There is no need for additional control connections, sensor tracks or user adjustments.

12200 Lenz LK200 Reverse Loop Module

This newly developed LK module was designed to fully automate the operation of both simple and complex reversing sections Wiring is very simple. Check a Wish List. Including a reversing loop in a 2-rail DC layout leads to a short where the reversing loop ties lena the main line.


On NMRA DCC digitally penz layouts, the direction of the train is independent from the polarity on the track, therefore, the polarity of the reversing loop can be changed without stopping the train or changing it’s direction.
