One featured industry on my layout is going to be a grain elevator. I live in the heart of farming country here in Ohio, and have lots of inspiration for building one. Since my railroad is ultimately a tribute to my late grandfather, a farmer and N scale railroader, I feel that this industry must be a focal point. I already have a few NKP covered hoppers, but I also want some for my freelanced road. Who makes high quality unlettered N scale covered hopper cars? I want to paint these myself, in my road's colors. If you know of an online source, please let me know. I'm also looking for a source for dry-transfer N scale car lettering.
