Back in September, there was a thread here on the Tinplate forum about "Standard Gauge 6-drive-wheeled steam engines". In the discussion, Arno posted some photos of the Harmon and Thon 4-6-6-4 Standard Gauge Challengers, and I had a one-word response, "WOW!" That someone had basically hand-built something like that in Standard Gauge is pretty mind-blowing.
So I followed up on it: Arno introduced me to Bob Thon. Bob is an interesting guy, to say the least. He bought Roberts Lines Standard Gauge from Russell Roberts and continued to manufacture that line. He has also worked on some other amazing Standard Gauge projects: he marketed the big GG-1 developed by Robert Hendrich: and he acquired the design of the Harmon Challenger. Bob continues to build these, developing the design and adding detail, using a combination of custom-made castings, hand fabricated parts, and some off-the-shelf parts as appropriate.
A few years ago, Bob finished assembling one of these Challengers and started lugging it around to shows and SGMA events. He didn't paint this one, leaving it "natural" so that the construction details - copper boiler, aluminum castings - were visible. And I mean "lugging" it! The Locomotive and tender are 50" long and weigh in at 60 pounds. Bob Build a special wooden box to pack and carry it in.
Long story short, Bob and I met up at York in October and I came away with the Challenger. It is Bob's #115, which I would say qualifies as fairly low production. This one is powered by two 3-axle McCoy open-frame traditional motors. Each of the motors is actually 2, having two armatures driving the three axles. And there's two of these units. It's the motor which was native to McCoy's "Chief Cle Elum" Ten-wheeler locomotive.
I actually really liked the unpainted look of the locomotive - the copper and aluminum is reminiscent of a long tradition in Standard Gauge of unpainted metal trains starting with Lionel's Brass #7 and continuing up through the Mayflower and Prosperity Special. But in the end I decided to paint it, which of course means completely disassembling the beast.
