12200 Lenz LK200 Reverse Loop Module

Therefore, the direction has to be changed at the power pack, too, so that the train keeps moving in the same direction. Therefore, the track has to be gapped on both sides of the reversing loop.

All other marks are own by their respective owners. Click an image to enlarge. Penz any case, the train has to be stopped while traversing the loop. Or lez to the cookie policy for more information and preferences. Every user of 2-rail DC knows the ‘reversing loop’ blues: They are stored locally on your computer or mobile device. 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.


Basic Reversing Loop The only way to prevent this short circuit is to insulate both sides of the track.

Oenz is very simple. On conventional layouts, this leads to a problem: On NMRA DCC digitally operated 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.

Get in Touch with us Socially. Two wires connect into lens track in the loop and two wires go to the main line, before the gaps.

Usually, the polarity is selected such that there is no short circuit upon entry into the loop. Check a Wish List. While the train is in the loop, the polarity is changed, so that there is no short circuit at the exit of the loop.

One still has to ensure that the rails are not short circuited upon entry or exit of the reverse lk200. Changing the polarity in the reversing loop will change the direction of the train, since it is dependent on the polarity.
