I started on my N&W Hi Hood C-425 Phase III today. The unit is an ATLAS Phase I with a Stewart C-630 Hi Hood and Cab. This modification was a little more involved than I thought it would be because the Stewart hood sits a little lower than the ATLAS does. I had to build up the bottom of the cab a bit with plastic. The cab steps are from an ATLAS Canadian Cab C-424 as is the fuel tank. I still have to make the battery boxes that go under the walkway.
