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. This newly developed LK module was designed to fully automate l2k00 operation of both simple and complex reversing sections Wiring is very simple.

There is no need for additional control connections, sensor tracks or lens adjustments. Basic Reversing Loop The only way to prevent this short circuit is to insulate both sides of the track.


Changing the polarity in the reversing lenx will change the direction of the train, since it is dependent on the polarity. They help us to know a little bit about you and how you use our website, which improves the browsing experience and marketing – both for you and for others.

Customer Reviews Create your own review. Including a reversing loop in a 2-rail DC layout leads to a short where the reversing loop ties into the main line.

Every user of 2-rail DC knows the ‘reversing loop’ blues: Get in Touch with us Socially. Powered by Cybertill supplier of retail software, EPoS systems and ecommerce solutions. On conventional layouts, this leads to a problem: Therefore, the track has to be gapped on both sides of the reversing loop. Click an image to enlarge. Temporarily out of stock – usually despatched within 28 days.

Usually, the polarity is selected such that there l2k00 no short circuit upon entry into the loop. Therefore, the direction has to be changed at the power pack, too, so that the train keeps moving in the same direction.

Two wires connect into the track in the loop and two wires go to the main line, before the gaps. All other marks are own by their respective owners.

Wiring is very simple. Check a Wish List. They are stored locally on your computer or mobile device.

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 loop.

This newly developed LK module was designed to fully automate the operation of both simple lebz complex reversing sections. 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.

The LK works according to the fault current principle, with track polarity reversal occurring at mA fault current.
