Status feedback

Status feedback contains information about:

  • whether a point is currently switched to 'branch' or 'straight' (LR101)
  • whether a track contact is activated (LR101)
  • whether a track is occupied (LB101, LB050)

Feedback with RailCom

RailCom not only facilitates the identification of a locomotive (i.e. the detection of the locomotive address), but also provides other data (e.g. speed, CV content, etc.).

Lenz 11201 LR101 Feedback module with 8 outlets

The most well known and commonly used form of feedback is information as to if a track on your model train layout is occupied or not. Even when you control your layout “only” by hand, you will surely want to know the status of tracks that can’t be seen. Hidden staging yards are referred to as “hidden” for a reason.

Feedback is absolutely necessary for fully or partially automated operation. How else will a computer program “see” if a particular track is free or not? This information is needed in order to know if a train may enter a particular track or not.


The feedback module LR101 has 8 inputs to connect switch contacts or occupancy detectors LB101 and 1 input to connect a voltage detector LB050.


To bridge unstable switch conditions (e.g. temporary interruptions of the power supply), each signal input can be assigned a programmable delay time for feedback on the occupancy status of a track. The status is reported to the command station LZV100 via the feedback bus. The status can be displayed with a manual control LH100 or a PC (via the Digital plus interface).

Lenz 11210 LB101 Occupancy module

In order to detect the status of tracks the LB101 functions as a current sensor, and is inserted between the LR101 and the monitored track section. The LB101 can monitor two track sections independently from each other.

General information about the LB101 Dual Occupancy Detector:

The LB101 contains two independent occupancy detectors, each of which can be used to detect that a train or piece of rolling stock occupies a section of track. It operates on the so called “current sensing principle”. The LB101 only detects occupancy when there is a "current consumer" within the monitored track section (detection section). The LB101 has been designed to detect a decoder equipped locomotive or a single car with lighting or resistor wheelsets.


When the LB101 detects that there is something it its detection zone, the LB101 closes an electronic switch. This switch can be used to trigger layout feedback devices such as the DIGITAL plus LR101 encoder,
or other low current electronic inputs such as those used to trigger some signal systems. The LB101 is compatible with all NMRA DCC systems.

Lenz  11220 LB050 Voltage detector for feedback module LR101 

Status detection via current sensors, such as the occupancy detector LB101, has one crucial disadvantage: if the operating voltage is interrupted, so is the power supply. In this case, occupancy detection fails: the signal output will report unoccupied tracks that are, in fact, occupied. Power failures may be caused when the voltage is switched off or short circuits occur which are a frequent phenomenon in model railway systems. The voltage detector LB050 was designed to prevent faulty feedback. It checks whether digital voltage is applied to the track; if not, the present status will be fed back until voltage is reapplied.

12200 LK200 Reverse-loop module
LENZ1220012200 LK200 Reverse-loop module

Lenz  12200 LK200 Reverse-loop module 

This newly developed module LK200 is safe due to fault current principle, polarity change takes place at 100mA residual current, indicated by LED. Switching is carried out electronically without  a relay giving high change speed and no mechanical wear. Wiring is very easy (like LK100), no additional control connections, sensor tracks or the like required. Maximum load capacity: 5A.

The LK200 is the real solution for reverse loops, triangles and turntables: easy wiring, high switching speed and as much safety as possible.  Make you reverse sections long enough to accommadate the longest train that will use them so that you do not bridge both ends of the insulated track at the same time.

The LK200 is not intended to switch polarity on the frogs (Vee) of Electrofrog diamond crossovers  (Peco SL-E193 SL-E194...)

Lenz 15105 LRC100 RailCom Transmitter Module 5 pack

Manual in German, English and French

One transmitter module LRC100 is required for every locomotive whose address is to be read out, unless the decoder installed inside the locomotive is already fitted with one of these modules. Simply connect the transmitter module to the locomotive's track contacts. Thanks to its compact size, the transmitter module may be installed in almost any locomotive.

Address Information is transmitted via the normal track connections.  This address can be made visible on suitable displays (eg the LRC120).  The contents of CV's may also be displayed.

All new Lenz decoders are provided with RailCom as standard. The LRC100 allows you to upgrade older decoders to give them this function.  The LRC100 module on its own provides no motor or function control.

Requirements for RailCom

The necessary "blanking interval" (also known as RailCom cut-out) must be activated in order to run RailCom  (activation instructions are given in the booklet provided with the RailCom Transmitter modules and with all new Lenz decoders).  You will need an LZV200 command station or LV103 amplifier to run Railcom. The LZV100 and LV102 can generate Railcom.  An older LZ100 (version 3.5 or later) may be used in conjuction with an LV102 amplifier in order to run RailCom. - (Please note that amplifiers LV100, LV101, LV200 and compact are unable to provide the Blanking Interval necessary for RailCom).

Lenz 15120 LRC120 RailCom Address display 

This 4-digit display serves to depict the address of the locomotive located in a monitored track section. Installation is possible anywhere on the layout, for example inside a signal box.  The LRC120 can be used to monitor hidden sidings.  One useful feature is that it allows you to confirm that a locomotive decoder is correctly set up to broadcast the RailCom signal.  We have used the LRC120 with Lenz, Roco Z21 and with Uhlenbrock POWER4 generated RailCom.
