What does this traffic sign combination indicate?

This traffic sign combination is a warning sign indicating a railway crossing. The small white plate with three red slashes below the main sign shows the distance to the crossing.

Each red slash corresponds to approximately 80 meters. Since there are three red slashes, this means the railway crossing is about 240 meters ahead.

This system helps drivers judge the distance to the hazard (the railway crossing) and prepare to slow down or stop if necessary, improving safety. Remembering that each slash equals about 80 meters can help you estimate the distance to the warning in similar German road signs.
