This park is totally awesome!!! It has one building filled with the different scales of trains constantly running. It was amazing to see how they put this together to represent different parts of Arizona. It must have taken years and it was worth visiting. I was also with family and my granddaughter and they has a small train for anyone to ride. My granddaughter loved this train. Unfortuantely, a few of their large trains were closed because of the heat in July. When I return in cooler months, I will definitely check out the large trains.
