Ireland’s biggest model railway is 240 sq metres, and authentically displays much of Ireland’s rail and public transport system, including the DART line and Irish Sea ferry services, in O-gauge (32mm track width). A separate room features model trains and other memorabilia. Unfortunately the operators suffer from the overseriousness of some grown men with complicated toys; rather than let you simply look and admire, they herd you into the control room in groups for demonstrations.
