The electrification of railways in Poland was a process aimed at increasing the efficiency of railways by implementing electric rolling stock and replacing steam traction locomotives, and improving the services offered. By the end of the 1970s, thanks to massive electrification and the introduction of a large amount of electric rolling stock into service, it allowed to replace a large number of steam locomotives and older diesel rolling stock. Despite the abandonment of works in the 90s, currently PKP and other entities managing the railway infrastructure, such as PKM or DSDiK, are working on the implementation or are already implementing the electrification of their lines. Currently, the electrification of railways in Poland is aimed at improving rail transport by increasing competitiveness and attractiveness and replacing diesel traction of national importance and saving fuel on regional lines and railways mains such as line 31 from Siedlce to Siemianówka, line 137 from Kędzierzyn-Koźle to Legnica and line 203 from Tczew to Kostrzyn.
