Fire Station in Em4 build

Hello, I need help building a fire station and positioning the vehicles so they can return to the station.

Hallo benötige Hilfe beim Bauen einer Feuerwache und der Setzung der Fahrzeuge das sie wieder zurück in die Wache fahren

I don't know how to place the points,
or how to get the vehicles to drive back to the station.

It is about permanently stationing vehicles at a Fire station.
