What do these traffic signs indicate?

The traffic sign with a train symbol inside a red triangle warns of a level crossing ahead. The additional sign below with the arrow shows that the level crossing is on the road turning right. This means you need to be extra cautious when you reach the point where the road curves right, as there will be a railway crossing there.

In German traffic rules, the warning triangle indicates a potential hazard—in this case, a railway crossing without barriers or signals. The directional arrow helps you understand precisely where this hazard is located relative to your current direction. It’s important to slow down and be prepared to stop if a train is approaching.

This sign does not show from which side the train is coming nor indicate a diversion; it simply warns about the position of the level crossing on the road ahead.
