The final box-stock holdout among my modern locomotives has at last been sent to the scrap heap and from its remains, new life has sprouted forth!  The build of this switcher did not go at all as I had planned; it actually went much better.  About a third of the way through I made a pretty significant change to the design concept that turned everything around (both literally and figuratively) and led me down the path to a very different aesthetic style than I expected to pull from these parts.  What started out as a string of experimental failures, then, morphed into something very unfamiliar, yet personally satisfying.
