Children are enthralled by four enormous scale train layouts depicting historic California railroad lines, complete with miniature trestles, tunnels, glowing city streetlamps, and chugging freight trains. The interactive 'Toy Train Gallery' allows toddlers to press buttons to control model trains, sound whistles, and operate track switches. The museum provides elevator access, wide aisles, and a dedicated stroller parking area. ## Similar picks in San Diego - [San Diego Natural History Museum (The Nat): Fossil Mysteries & Paleontology](https://grassyknees.com/san-diego/activities/san-diego-natural-history-museum-the-nat-fossil-mysteries-and-paleonto--listing-42fdfffd8c3aaf5967561474) — Open daily 10:00 AM – 5:00 PM; Closed only on Thanksgiving and Christmas Day · San Diego Natural History Museum (The Nat) · All ages · From $24 · checked Nov 4.
