Here are some quick snapshots of highways created with Gimp (open source Photoshop workalike) and printed with an InkJet on matte or "canvas" photo paper.  Scenes are not all complete.

When I started to build my layout four years ago, I used Atlas flextrack by default simply because it was the only product of its type that was readily available in local hobby shops.  At the moment, however, no local hobby shop has the Atlas product in stock.  All contend that it is not in production.

Which has led me to explore flextrack manufactured by Peco and Micro Engineering.

If you want to achieve perfect track work, buy yourself one of the very small levels that masons hang on a level line.  Mounted on the back of a slow moving gondola or flat car, it will reveal imperfections in track work that simply do not show up on longer levels but which can make a bit difference in the smoothness of train operation.  I've found my mason's level especially helpful when having to work out transitions to and from super-elevated curves, especially one long climbing "S" curve that once drove me nuts with passenger car derails.

I've attached a few mobile phone photos of my in-progress 25x25 freelanced dogbone layout, inspired by the New York Central Railroad as it existed in the Mid-Hudson Valley in the late 1940's and early 1950's.   I hope to have a "rough draft" completed by spring, then will begin detailing and adding a helix to a lower-level staging yard.
