I won't explain the basic functions of the editor in here, if you need help with that, press 'F1' while in the editor and you'll get a brief description of what to do with it.

Before you start throwing elements on the track, you should enhance the grid. Press 'Esc' and choose 'adjust'. Use the cursor keys to bring the grid to full size (20x20). The reason for this is that you should always use the largest possible grid for the track. Later on you'll see that even this size is too small sometimes.

Next step should be to decide whether you want to make a single or a double sized track. Check the next section for further info. But I recommend to make this decision before you start building.
