Just bought the new version 6 of AnyRail, planner. It has a few additions to the original, like tunnels, bridges and embankments. There are a couple of 3D rotational views too.
I have a small round-and-round planned, so it can be easily packed away, so I have some pictures of that, as it isn't as complicated as some.
I have some samples just run off from existing plans. The first picture is a larger plan with a climb, embankment and a bridge. The second shows a different texture to the grass and you might just make out a tunnel far right. It also has options for track looks and stuff like ballast choices too.

New but better to get an idea of the plans
