Could be a locomotive, accessory, scenery, a photo, a video or something else model railroad-related.
I will start us off with this video I took this morning:
The reason I chose the above is that the locomotive is so perfect for my layout. It was custom made for a terrific hobby store, JR Junction Train & Hobby from Syracuse, NY (one of our Forum Sponsors), to sell to its customers, and that hobby store donated part of the sale proceeds to a railroad historical society. The locomotive is an MTH Railking Proto 3 that looks, smokes, sounds and runs great, especially on my layout with sharp curves.
