A new way of controlling model railroads by modelers for modelers.
project is developing an easy but sophisticated network for model
railroad control using today's technology.
It is the
basis for NMRAnet / S-9.7 Standard bus.
website describes OpenLCB, a developing Local Control Bus (LCB) used
to control model railroad accessories. It is designed
to make set-up of simple and complex layouts easier. It is not meant
to replace DCC, but rather work along side it. It makes your operator
consoles, CTCs, and accessories more effective by bringing everything
together into one system. Your investment in DCC, CTC, signals and
turnouts is protected. Cabling and connection is simple and low cost
--- and usually pre-made but can be DIY assembled needed. Bus wiring
consists of a single network cable and a single power supply cable.
Configuration is simple and easy to manage.
see how this works, look at the second video on this
– which shows how things are actually programmed. The third video
shows some more-complex programming. You can re-use things you have,
like signals, BOD's, turnouts, train ID sensors, RFID, structure
lighting and the like, but connect them in ways you never thought
possible, to achieve full prototypical accuracy and detail. Add
complex new technology easily, such as sound effects, TV in
structures, timetable signs in stations, outdoor video displays,
structure lighting fully controlled and much more as time goes on.
Hopefully different manufacturers will support a common standard and
so the range of products available will grow.

its July 2011 meeting, the NMRA Board decided to proceed with NMRAnet
/ S-9.7 based on OpenLCB designs.
OpenLCB group did two
OpenLCB clinics at the NMRA 2011
convention in Sacramento. We've posted the slides
from the clinics if you couldn't be there. We've also got a page
of movies, photos and diagrams from the day's worth of
demonstrations we did at the NMRA 2010 convention in Milwaukee.

What we're doing:
OpenLCB is being developed through an
open, community based process. You can follow our
documents as they develop, check out our prototype code, and if you
want to take part.
Welcome to the project! We all benefit

How to get
prototype hardware is based on:
* the AVR-based Arduino
platform at Hobbyists,
a ATMega328-based compatible from Silicon Railway;
Shield from SPCoast;
Developer's Board, an AT90CAN -based compatible from Railstars,
an Arduino-compatible AT90CAN-based board also from Railstars
as a platform for a throttle and a command station, and its
a library for a Command Station, from Railstars;
* the new DevKit
from Railstars / NMRA.
* PIC code based on the CBUS platforms
is a CAN-based layout control bus being developed by MERG.
The NMRA has an effort to create an
“NMRAnet” layout control bus standard. OpenLCB is being proposed
for that. Currently, the NMRA is focusing the NMRAnet discussions on
a common standard for CAN physical layers. For more information on
OpenLCBs work on NMRAnet, our NMRA
