A few general settings control how track appears on your screen. You can find these in the Ribbon Home tab:

Example 1: Centerline

Example 2: Track

Example 3: Sleepers

NOTE: AnyRail displays sleepers for aesthetic reasons, only. The position shown is not intended to be exact, though the width is correct.
Example 4: Centerline with roadbed

NOTE: To avoid disappointment, use this option to check that the roadbed fits on your train table and that the tracks are not too close to each other.
