Extensive layouts, and varieties of trains, all HO scale, I think. Obviously carefully crafted by loving volunteers. They host several open houses a year, and let youngsters take turns "driving" the model trains (with adult supervision, of course). As the trains are all on elevated platforms, this is not suitable for anyone in a wheelchair. Some movable steps are available, but be prepared to lift and hold smaller children. Admission was by donation when we visited.
