From the developer:
Cadrail is a powerful CAD program with many different railroad design tools. You can create track plans of any size and shape. There are easy-to-use drag-and-drop tools that allow you to snap track sections together end-to-end and align them automatically. Flexible CAD tools let you create complex shapes that your train will run on and that you can build.
