Idea, ask these guys:
- National Park Service runs Golden Spike Park. Locos there are replicas they had built.

National Park Service said:
Are these the original locomotives?
No. These are replicas built by O’Connor Engineering of Costa Mesa, California in 1979. They are within one-quarter inch of actual size, and are fully functional in all respects.
What happened to the original locomotives?
This size and type of engine was outmoded and under-powered by the turn of the century. There eventually came a time when they just were not worth repairing any more. The No 119 was scrapped in 1903 for about $1,000, and the Jupiter met the same fate in 1906.
Were the original engines really that shiny and colorful?
Yes. They were built during the Victorian Age, and reflected the designs and craftsmanship of the era. The locomotives were both the workhorse and advertising of the railroads.
