XTrackCAD is a CAD (computer-aided design) program for designing Model Railroad layouts. XTrackCAD supports any scale, has libraries of popular brands of turnouts and sectional track (plus you add your own easily), can automatically use spiral transition curves when joining track and has extensive on-line help and demonstrations. XTrackCAD lets you manipulate track much like you would with actual flex-track to modify, extend and join tracks and turnouts. Additional features include tunnels, 'post-it' notes, on-screen ruler, parts list, 99 drawing layers, undo/redo commands, bench-work, 'Print to Bitmap', elevations, train simulation and car inventory.

Using it, you can

Design layouts in any scale and gauge,
Use predefined libraries for many popular brands of turnouts to help you get started easily,
Add your own favorite components,
Manipulate track much like you would with actual flex-track to modify, extend and join tracks and turnouts,
Automatically generated Cornu transition curves (easements) whenever the track radius changes.
Test your design by running trains, including picking them up and moving them with the mouse.
Trace tracks and other objects over a background image of a real-world location map, a scanned trackplan, or other image.
Print the design in a scale of your choice. When printed in 1:1 scale the printout can be used as a template for laying the track to build your dream layout.

New users should run the demonstrations (via the Help>Demos menu) to get an overview of the many features of the program. A number of example layout designs are also available.
