Just wanted to introduce myself - I've been collecting N-scale models for a while; haven't considered a permanent layout yet, but every so often I'll set up some unitrak to run trains. Being in my mid-20s, I grew up watching the UP and BNSF swallow up the SP and ATSF, but I have a soft spot for the golden age of passenger trains, particularly the 30s and 40s when steam was still king. I'm mostly a Santa Fe modeler, and sort of a long-term project is to assemble various name trains as they were in the 1940s (Chief, Scout, California Limited, Grand Canyon).
I've also dabbled in V-scale (mostly Microsoft Train Simulator, at one point modeled an ATSF 3700 class 4-8-2), but have been going back and forth between that and n-scale - with Shapeways I'm planning on doing more 3D modeling for n-scale.
I look forward to sharing some of my own projects, and hope to learn alot from this forum!
