This thing looks good, I need one for my collection.
I would try to turn down those flanges on those wheels especially if you don't want to be stuck on code 100 track. I have had luck with a dremel on various AHM/Rivvy 0-4-0's but just spinning them while they were clamped to something upside down but I have found that the more axles there are the harder it gets.
On that note, if anyone has seen one of these or wants to thing their collection give me a shout.
Nevermind. A little more stubbornness, or persistence, paid off. The body needs to be squeezed slightly wider to allow the motor to be extracted; the glue I thought was holding the chassis to the back of the cab, turned out to all be body-to-cab.
Now this I can work with. At the very least, need to install some pickups, both on the drivers (one side only) and in the tender (again, one side only). Plenty of room in the tender for decoder and a big speaker, drill some small holes all over the coal load to let the sound out, plus maybe some in the base of the tender. Clean the whole thing off, then ever-so-slightly "dirty" it up with a little weathering.
I've got my next two months of spare time laid out. :-)
