The two Golden Spike replica locomotives "live" in a 2-stall engine house, located at the east end of the park. The facility is quite spacious, with all of the facilities needed for both routine and heavy maintenance. The former is typically done by the regular crew of Park Service Employees, while more extensive maintenance is done by specialty contractors from within the region. Although the small railroad at the park is totally insular, it is Federal property and so the park has elected to maintain both locomotives under FRA rules, which means 49 CFR Part 230. Both locomotives have current Form 4s and undergo the same periodic inspections, including the extensive 1,472 Service Day Inspections that steam engines on regular tourist railroads are required to have. The crews report that after 40 years, both boilers are holding up well and that no major components, other than flues have required replacement. Of course, the engines are rather lightly used, never pulling any trains, and running relatively few miles, so one would not expect a lot of wear and tear. Although they are not originals, these locomotives have now seen service lives that are longer than many engines did back in the day. In fact, when the 200th anniversary of the Golden Spike rolls around, these two engines will be about 90 years old.
