In this article we shall learn to create a crossroads and a double or cross switch.

Let's try to create these objects on a usual example.

Lay two pieces of a track under a small corner between them, as shown on screenshot.

On the main menu, the left window above, press button , above a place of a crossing there will be a grey cube, apparently on screenshot.

Guide a mouse on this cube, and press the left button once, your simple перекрестие ways it will be changed to a crossroads, apparently on screenshot.

If you will press the not disappeared cube once again, your crossroads will be changed in a double or cross switch.
