Recently I packed up my large steam engines and swore that I would only run small to medium at best steamers on my layout due to its 22" min radius curves. The larger steamers will return one day when I have tired of the present layout and decide to build a new layout with larger curves.
Well, after seeing pictures of the new Athearn MT-4 Northern at the Anaheim 2008 NMRA Show. I can not help myself I must purchase one as soon as they are available. They are one magnificent engine and Athearn has out done themselves with the detail on this engine.
