LRC RailCom local Address Display

Introduce RailCom to your layout! Read out the address of locomotives and their CV's. RailCom is a new and innovative Lenz technology for allowing a locomotive to transmit real data to include its address and other operational information anywhere on the layout independent of whether it is stopped or whether it is in motion!

RailCom allows an external device to be able to read real data transmitted from a decoder.  This data can include the decoder’s actual speed, its load, its location, the contents of CV and it its address.

One special advantage of the RailCom technology is that no additional components have to be installed on the outside of the locomotive. Regardless of where the RailCom decoder is installed inside the locomotive, this does not impact data transmission.

To take advantage of the bi-directional features in RailCom, it is not necessary for the locomotive to stop or move at a precise point on your layout to transmit information. No receiver components disturb the appearance of your layout since any information is transmitted via the normal track connections.

To enable the bi-directional features of RailCom you need three components. 

  1. A decoder that transmits the information such as a Gold Series Decoder.

  2. A detector that can receive these transmissions such as the LRC120

  3. A cutout device that conditions the track for the transmission such as an LZV100 or LV102.

Using the LRC120 Local address display

The RailCom technology has been developed and patented by Lenz Elektronik GmbH. To use RailCom with your model railway, some requirements need to be fulfilled:

The address display LRC120 shows the address of a locomotive in a track section connected to the LRC120. This track section may be located at any point on your model railway layout.

Requirements for using the LRC120 address display

To display a locomotive address with the LRC120, the locomotive must be equipped with a RailCom transmission module and the transmission must be activated. The GOLD decoder series is equipped with such a module; all you have to do is activate the module by setting the respective CVs (CV28 and CV29). If your locomotive is already equipped with a different decoder, you may install the RailCom transmitter module LRC100 in addition to the existing decoder. In this case, the LRC100 is programmed to the same address as the existing decoder.

For the LRC120 to display the address, a RailCom capable power station must be used.  Within the Digital plus family, only the LZV100 or LV102 power stations currently have this feature.
