The PKP EP07 1012 seen hauling a flat price TLK75110 fast train between Łęgowo Sulechowskie and Babimost

This fast train is heading to Gdynia on the Baltic Sea from Zielona Gora, and this little branch line is the fastest way to do that. Zielona Gora lies on the Wroclaw-Szczeczin main line (in Prussian times: Breslau-Stettin) and this line means a shortcut to the Berlin-Warszaw railway. To help you orient yourself, I am adding a small map:

Railway network around Wolsztyn, Poland (click the map to see entire Northern Countries map of benbe.hu)

The horizontal line on the top is the Berlin-Warszawa line, the Zbaszyn-Wolsztyn line is the one on which we had photographed the steam train earlier, this electrified branch line is on the left-hand side of the cutout, the normal route of the steamers to Leszno is below Wolsztyn (which is almost in the middle) and the Saturday path to Poznan can be seen almost horizontally to the left from Wolsztyn. Not shown on the map are the draisine line (standard gauge) from Grodzisk Wielkopolski to Koscian on the Poznan-Leszno line and the mostly impassable narrow-gauge line from Stare Bojanowo to Wielichowo (tourist trains occasionally run as far as Smigiel).
