Not a lot of visible progress, but work on the Arduino projects and on the ductwork continues. Here's photo of all the trains that I moved out of the Staging Area so as not to get dirty. Right in front is the new Alco S-2 (awaiting its Weirton Steel paint job). After that are the 2 Decapods, the E-7s and their passenger consist, and the 2 K4s.
More when I know it.
