The coordinates given are for our example only. What you must do to log this cache is find a surviving Steam Locomotive. It does not need to be in working condition, but can't be a model or small-scale locomotive! They can typically be found in city parks, museums, theme parks and excursion railways, but may be located almost anywhere.
To log your find you must upload a photo of the locomotive, report the coordinates, the location (city, state, etc.), the railroad name and locomotive number (if available) and, optionally, any other information you find. You must take the photo for this cache - old vacation photos and photos downloaded from the web don't count.
You may only log this cache once, and can't log a locomotive that's already been logged. There are nearly 1,400 in the United States alone.
Our example is the Spokane, Portland & Seattle Railway No. 539 located in Battle Ground, Washington (N45°46.895 W122°31.683). It is a 2-8-2 oil-fired Mikado type locomotive. It operated in the Northwest until the late 1950's. It was retired to a park in Vancouver, Washington where it remained for forty years before being moved by truck and rail to it's present home. It is currently undergoing cosmetic restoration.
