For those of you that enjoy the railways and its history. This engine is one of the WAGR S Class built between 1943 and 1947, also known as Mountain Class Locomotives. They were designed by Frederick Mills and even have what is known as Mills wheels. These locomotives were built in the Midland Workshops and there were a total of 10 made but only 3 still remain. All were named after Western Australian mountains. The tender attached to this engine was originally with Lindsay (547) another of the Mountain Class.
This cache should be easy to find, this is one of those caches that is more about the site than the hunt. There is no need to reach inside the fence, the cache is on the outside in the obvious spot. Oh and BYO pen.
