I have looked on the particular train website but can't find anything that shows the stops on the journey.
It is easy. Klick on the "rozwiń" inside the train connection, then click "zobacz pełną trasę" and you will see all the stops along with the times of departure:
Wrocław Główny - W. Muchobór - W. Nowy Dwór - W. Zerniki - W. Leśnica - Mrozów - Miękinia etc. etc.
Twelve minutes between W. Główny and W. Zerniki
