Empire Express is a model railroad designer for Mac OS. The program allows you to easily, and accurately design your model railroad empire. Designing a layout is as simple as dragging track and structures from the catalog palette to the plan window. Track pieces are automatically aligned to create accurate, kink-free track connections. Flex track can be easily bent to create smooth curves which meet the user-selected minimum radius standard. The tool palette includes line, rectangle, circle, polygon, and text tools which you can use to draw the layout room, structures, and scenery.
