Commissioned by CIE in the early 1980s to promote the proposed electrification of the Howth to Bray railway line this layout is older than the DART itself. To mark 40 years of the DART service the South Dublin Model Railway Club has refurbished the layout, upgrading the scenery including buildings and installing operating colour light signals.

At the recent Model Railway Society of Ireland exhibition the layout was on display. Murphys Models launched their proposed new model of the Alstom DART units. The prototype was displayed on the layout.
