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.
Successes in the further work.
