Taking the kids to San Diego Model Railroad Museum? Bring Rally along.

In Rally Takes the Train, a corgi's little legs can't manage the big train stairs, so Dad gives him a boost. It takes about five minutes to read, a good fit for the drive to San Diego.

From a 1935 exposition layout to a museum of miniature California

Model trains have a long history in Balboa Park. At the 1935 California Pacific International Exposition, pioneer modeler Minton Cronkhite designed a 40 by 70 foot O scale model railroad that was billed as the chief transportation feature of the fair. Railroads such as the Santa Fe and the Pennsylvania hired him to build giant layouts for world's fairs, hoping to stir interest in train travel during the Great Depression.

The museum itself opened in 1982 on the lower level of the Casa de Balboa, with a mission to preserve railroad heritage through miniature versions of California railroads, research the history of model railroading, and teach the public about railroading. Nearly three million people visited in its first three decades, and its 27,000 square feet make it one of the largest model railroad museums anywhere.

What makes it work is the clubs. The big layouts were built and are maintained by four local nonprofit groups: the San Diego Model Railroad Association, the La Mesa Model Railroad Club, the San Diego Society of N-Scale and the San Diego 3-Railers. Members have spent years on details like the Tehachapi Pass layout, modeled from thousands of photographs of the real line nearly curve for curve and switch for switch.

Today the museum is a 501(c)(3) nonprofit with education staff, school and scout programs, summer camps and a reference library, and it describes itself as the only model train museum in the country accredited by the American Alliance of Museums.

Mountain passes, desert gorges and a toy train gallery

The museum is home to two massive HO scale layouts. The San Diego & Arizona Eastern, about 4,500 square feet, follows the real line from San Diego Union Station east through Carrizo Gorge to the desert floor at El Centro. The two-level Southern Pacific on the Tehachapi Pass recreates the joint Southern Pacific and Santa Fe line from Bakersfield to Mojave in the 1950s, including the Tehachapi Loop.

The 2,700 square foot Cabrillo & Southwestern in O scale imagines a route from San Diego to Sacramento, and the 1,200 square foot Pacific Desert Lines in N scale models a railroad that was surveyed but never built, with 33 scale miles of hand-laid main line. The Toy Train Gallery runs Lionel-type 3-rail trains on four main lines and displays rare Lionel and American Flyer cars from the 1920s to the 1950s. There is also an exhibit called Freight and Flora, plus a non-circulating library open to any visitor.

Push the button, watch the train go

The Toy Train Gallery has an interactive layout where children push a button to run a train, a hands-on stop for the youngest visitors. Older kids can follow trains through tunnels and over trestles on the giant layouts, and the museum builds STEAM learning into its programs, from Trains & Tots for little ones to school programs, scout programs and summer camps.

Family days fill the calendar, including the Easter Eggspress, a Summer Kick-Off, Thomas Family Day, Trains & Treats at Halloween and a Polar Express Family Day in December. The museum is indoors, which makes it an easy pick on a hot or rainy Balboa Park day. Groups of children under 13 need one adult chaperone for every four kids.

Bring Rally along: a train book for the drive

From Rally Takes the Train, watercolor by Leslie Dunn.

The model trains here disappear into tiny tunnels and pop out on the other side, and I can just hear the little gasps. Rally's train in our book does the same thing on a bigger scale: a dark tunnel, then a big bright light and happy cheers. Our book's train is the Pacific Surfliner out of San Diego, so this museum feels like a neighbor. Little readers can find that tunnel in our picture book.
