I use a commercial CAD package, called Visual Cadd, for which I paid
only $99. It runs under windows. They're in Compuserve as Go Numera.
The features I value in cad software for layout design include:
1) Snap to construction point. A construction point is typically
the end of each line. Ability to snap a new line exactly on
the end of an old line is essential to accurate track designs.
2) Snap to: parallel, perpendicular, and tangent. Used w/sidings,
yards, and curves.
3) Component libraries. Lets me draw and save track templates
in a library so I can re-use them later.
4) Layers. Lets you design benchwork on one layer and track on
another.
5) Import/export in .dxf format (autocad).
6) Windows based, which assures printer and video compatibility
over an extended period of time wherein I may be changing
hardware.
I've built a decent sized library of track components; I chose to draw
track w/ 2 lines (0.649" spacing for HO). This has been very helpful
in many ways. I also built a component for a boxcar so if I want to
get a sense of spur capacity, clearance points, etc, I've got something
to measure with.
Hope this helps.

I have been using AutoCad Lite for planning purposes. I build blocks for all
the common point aand track types and then mix and match.
A good way to make sure that everything fits.
