I was looking through American Locomotives 1900-1950 by Edwin Alexander (c. 1950) and came across a locomotive that defines an odd-duck, the Union Railroad's 0-10-2s first built in 1936 by Baldwin. The Union served Pittsburgh's steel mills and needed heavy switching power. Shop and turntable restrictions limited length, so the front truck was jettisoned, but the rear truck retained to support the large firebox. Note too that a tender booster was included in the design. These were known as Unions and they were the only examples built. My Dad gave me the book when I was nine and he educated me in wheel arrangements that same evening. It hardly seems so long ago.
There's a pic in Iron Horses of the Santa Fe Trail of an early Santa Fe 2-10-2 with its pilot truck missing. Maybe it, too, was being used as a heavy switcher; they were (the only survivor switched the Phillips refinery at Bartlesville). Anyway, the caption says, "...here's proof an 0-10-2 existed." I guess they never heard of these purpose-built beasts.
Most of the Union RR's fleet of 0-10-2 locos eventually went to the DM&IR. http://www.rr-fallenflags.org/dmir/dmir-s604dsa.jpg
Now that you've mentioned it, I seem to recall a video posted on YouTube, (or similar site?), which shows these in DM&IR operation.

It looks a lot like many Lionel or American Flyer locos on eBay being sold as "Rare, Complete, and Excellent". Doug
That is... something. The fact that it has no pilot wheels, the tender looks a little small for the actual engine, and the enclosed cab makes it a strange type of engine. Nonetheless great photo of this extinct beast.
Not unusual for a switcher for service in a northerly climate. Ten drivers and a rear truck may be, but those other things aren't.
I believe the Union still exists as a active carrier in the 21st Century and its flag is still carried high.
I would imagine crews on the Missabe Road particularly appreciated the enclosed cabs. As a side note, Grand Trunk Western had some 0-8-2's converted from old Mikados at the Battle Creek shops, so I'm thinking this may not have been as uncommon as you would think.
