This is my first post. I work with Corel for my models. I don't do 2d, only 3d. I've been working on a GP40-2 in Western Maryland paint for about a year now. The prototype build will be HO, but I think I'll do the final in O scale to show more detail. If anyone is interested in this model, I can write instructions as I go. I'll try to post some pics when I get home. (I travel a lot) Since I live in the USA, does anyone on here model American Trains? Cool site btw. I've looked for a long time to find a paper train site!! btw, the GP40 is about 60% completed.
