Toy Train layout in Walnut Creek
Another great place to visit in the bay area is The Walnut Creek Model Railroad Society (WCMRS) operates the Diablo Valley Lines (DVL) model railroad, one of the most mountainous and one of the largest exclusively HO scale model railroads in the United States. This model railroad features standard gauge, narrow gauge, and interurban (overhead electric) freight and trolley lines. DVL Layout Diablo Valley Lines is exclusively HO scale (1:87). The equipment operated on the layout represents periods from the middle of the nineteenth century to the present time. Most of the modeled structures date from the 1950's when the transition from steam to diesel motive power was in full swing in the USA. The layout contains a standard gauge track and a narrow-gauge track. Only the train ferry Ramon, as seen in Mallard, represents a place from real life. The overall theme is a composite of the mountainous area of the Western United States.
