The Tehachapi Pass

by the La Mesa Model Railroad Club

The La Mesa Model Railroad Club operates the Southern Pacific-Santa Fe Tehachapi Pass Layout. This exhibit is a highly accurate replica of Southern California’s busiest single track mountain railroad and is HO scale. The Tehachapi Pass runs through the Tehachapi Range of the Sierra Nevada Mountains and is famous for the Tehachapi Loop, where because of the steep mountain grade the railroad was designed in a spiral loop. You can see this replicated on the mezzanine level of the Tehachapi layout.

Everything on this layout operates to scale. Including the types of trains run on the track, the times of operation and the speed.

The Toy Train Gallery

by the San Diego 3-Railer Club

The San Diego 3-Railer's Club operates the Toy Train Layout in the Toy Train Gallery. This fantasy layout features O Scale “Lionel Type” toy trains running on 3 rail O gauge track. One of the highlights of the gallery is the “Choo-Choo cam” fitted onto a running train which provides visitors with a first person virtual view of the layout. The exhibit was rated one of the top ten layouts by Classic Toy Trains magazine in 2012.


The Centennial Railway Garden

This exhibit was built to commemorate the 100th anniversary of Balboa Park in 2015. The G scale garden railroad is modeled after Balboa Park as it existed in 1915. G scale is about 1/32 to actual prototypical scale. The exhibit is solar powered and the plants are drought tolerant, making this display one of the only green technology exhibits in Balboa Park. The trolley cars that run on the layout are modeled after the Class 1 Street Car which was created specifically for the 1915 Exposition. The buildings were made using laser cutting and 3-D printing. The Balboa Park Online Collaborative created the interactive iPad and smart device elements which allow you to control lighting and sound on the buildings.
