Old Vegas was an amusement park at 2440 South Boulder Highway in Henderson, Nevada, located in the Las Vegas Valley. The park's theme was American Old Western, modeled after 1850s Las Vegas. The site included various amusement rides and a replica of Las Vegas' Old Mormon Fort, which contained the Hondo Casino. As of 1979, the casino accounted for half of Old Vegas. The park also featured several relocated buildings from the former El Rancho Vegas hotel on the Las Vegas Strip. The Eureka Locomotive was also on display at the park during the 1980s. Old Vegas was developed as a sister property to Old Tucson, a similar theme park in Arizona.

The Eureka is a privately owned 3 ft gauge steam locomotive based in Las Vegas, Nevada. It is one of three preserved Baldwin class 8-18 C 4-4-0 locomotives in the United States, of which it is the only operable example. It is listed on the United States National Register of Historic Places.
