The town of Calico was bought and rebuilt from the ground up in 1951 by Walter Knott, the owner of Knott's Berry Farm, as a ghost town tourist attraction. A tourist railroad was planned to be built to revive the history and legacy of the old Waterloo Mining Railroad. The narrow gauge Calico & Odessa Railroad was built by Shafe-Malcom Enterprises in 1954. It loops around one of the mountains nearest to Calico Ghost Town to one of the old silver mine shafts and the site of the former eastern portion of Calico. The line is operated by a single 0-4-2 steam-outline diesel locomotive.
