Press N to switch any rail planner to a "straight only" version that can't make turns (and press N again to switch back). This works on diagonal and half-diagonal rails too.

This is useful to ensure the game won't suddenly change to a roundabout path if you move your cursor slightly.

Compatibility

• Elevated Rails - You can still press G to switch rail layer too.
• Legacy Rail Planner
• Cargo Ships - Works with Waterways
