Create model railroad and slot car layouts on your Mac

Build your layouts by simply dragging tracks from the libraries and plug them together right on your Mac's screen! Try different variations, organize layouts into layers, assign different heights and grades to tracks. Preview Preview layouts in 3D - even with automatic terrain - and finally print in full, 1:1 scale.
