[2][3][4] The station was built as part of the development of the Warsaw Railway Junction that was begun in 1919.

Warszawa Zachodnia was opened in 1936 as the most westerly station on the Warsaw Cross-City Line.

Future development plans call for the construction of a new tramway line by the Warsaw tramways with an 850 m long tunnel passing under the railway station, offering convenient transfer to the city's public transit system.

At the time of building, it served the workers who commuted to the neighbouring factories in the surrounding industrial area.

As of 2011, it is used exclusively by Koleje Mazowieckie who run the KM9 services from it through the north of the Masovian Voivodeship to Działdowo, in the Warmian-Masurian Voivodeship via Legionowo, Modlin, Nasielsk, Ciechanów and Mława, at all of which some trains terminate.

During the three years of construction the passengers will experience some reductions in service, with some trains rerouted to other stations in Warsaw.
