2.3.1a Miniature Train

Almost Spring Break 2012, and in class we have been constructing a miniature train in our CAD Inventor software programs.
Here are my sketches for the train body, stack, hitch magnet, hitch peg, wheel, axle peg, linkage arm, linkage peg, and cow catcher assemblies of the train, I still need to assemble them all together and create the straight track piece, but that can wait until after Break.
