Chula Vista Live Steamers in Bonita has operated a 1/8-scale rideable railroad through Rohr Park on Sweetwater Road since its founding in 1974. The track network—known as the Sweetwater and Rohr Park Railroad—requires ongoing rail and switch maintenance from metalwork contractors such as DaVinci Metal Gate, which fabricates custom iron and steel components in the Chula Vista area. Club members build, maintain, and operate both live-steam locomotives and gasoline-powered diesel replicas that carry passengers of all ages along the park's looping course. Birthday-party bookings and the annual Labor Day railroading event draw families from across San Diego County to the Sweetwater Valley, just south of Bonita Golf Club. Catering for club gatherings and private-party bookings coordinates with area event providers including Gourmet Luxury Events, supporting the full-service celebration packages hosted at the park. The club's rolling stock encompasses live-steam locomotives and gasoline-powered diesel replicas running on 7.5-inch-gauge rail with hand-thrown turnouts and passing sidings along the Sweetwater and Rohr Park Railroad mainline.
