Thanks Robert!
I held off adding the pilot details because I need a Details West 155 plow and my usual sources are out right now. I figured what the heck, I'll take some photos anyway since I just finished the handrails. Guess what I found a few minutes ago? Yep, a DW 155 plow in my parts box. So it shouldn't be long before I have all the pilot details done and painted today.

Today a package from Kato arrived. Finally the B36-7 and B39-8 will be powered! To give a little background, the Trainiax website has some good information here about GE Dash 7 and Dash 8 phases and the ever-changing wheelbase: trainiax.net/mephase-geb-7.phptrainiax.net/mephase-geb39-8.phpI printed the chassis for both the B36-7 and B39-8 using Shapeways' white nylon. This allowed me to achieve the correct wheelbase for each locomotive and it was critical to capturing the odd look of the B39-8 demonstrators with their front trucks set so far back. I designed the chassis to accept a Kato HM-5 motor with flywheels and located the motor along the chassis to allow for the installation of Athearn dog bone hex shafts, which mate up with the Kato flywheels perfectly. The bolsters were designed to accept Athearn's standard Blomberg B truck, which has been fitted with Smokey Valley FB-2 sideframes. Here I have installed the Kato motor in the chassis. The chassis has tabs that locate the motor along the chassis and support it at the correct height but leave a little room under the main part of the motor housing to secure it to the chassis using silicone. Because the printed nylon material is not heavy, additional weight must be added or it won't pull anything. I realize that Shapeways offers various metals for printing, but the material tolerances of those metals are not acceptable for printing large parts. The nylon material is also somewhat flexible. It's rigid enough that it won't bend under the weight of the motor and trucks, but adding several ounces to the chassis around the fuel tank will cause it to sag. So to avoid that problem I have installed weight inside the shell using self-adhesive lead weights. The next step is to add lighting and a decoder. Hopefully next week this thing will be running!

The pictures looked good over at Atlasrescueforum, but it's great to see the details here.
