Here is a recent acquisition from an American Flyer Train Collection Estate.  This was something I had
never seen before in S-Gauge.  It was labeled as a American Hi-Rail  Locomotive Kit of the
New York Central Dreyfus J3a Hudson Steam Locomotive.
Here is the Right Side View of this Nicely Detailed Locomotive.

 

Here is the complete side view of the locomotive.
The Locomotive Shell and the Tender Shell with all of the Decals and Handrails were included in the Kit.
All that had to be added was the Chassis of a Pacific Locomotive with Smoke and Choo-Choo.
What a Cool Model of this Locomotive and in S-Gauge too!
