Little Siddington is the club's O gauge layout.
The layout was first exhibited at the 2018 WMRC Easter Exhibition and has since been shown at model railway shows in Wexford, Cork, Dublin and Belfast.
The layout is based on a country station and goods yard which provides operational interest. Trains on the layout are operated using the Roco Z21 DCC system via an app on the operators personal phone, with each operator taking control of a train and driving it around the layout.
Under the layout there are more than 50 electronic control boards for controlling and monitoring points and signals on the layout, which operate on the MERG CBUS system. The layout is a work in progress with further scenic work, signalling and block detection to be installed in the future.
