This group is to facilitate the development of an new and open Model Railroad Layout Control Bus specification. See:

http://www.openlcb.org

The OpenLCB specification has been adopted as the candidate for NMRAnet, and as such is also referred to as S-9.7. It is being developed by modellers for modellers.

OpenLCB defines a common protocol for model railroad layout control that is transport agnostic, and suitable for a wide variety of transports including Ethernet, wireless, and CAN. An OpenLCB network can be a single segment, or many heterogeneous segments connected by active gateways.

The protocol design caters equally to the needs of small and large layouts. You can start with just two nodes straight from the box, without the need for special tools, knowledge or connection to a computer, but OpenLCB also caters to large layouts, such as museums and modular clubs, as it is designed interconnect multiple heterogeneous segments via gateways, and the protocol is optimized for transparent multi-gateway operation.
