Warszawa Śródmieście railway station is a railway station in Warsaw, Poland, in the district of Śródmieście. The station serves the suburban tracks of the Warsaw Cross-City Line and is used by regional trains run by Koleje Mazowieckie and Szybka Kolej Miejska. There are two side platforms and one island platform serving two tracks, all located in a tunnel.
It was built on the principle of the Spanish solution, whereas the centre platform would be using for the arriving passengers only and the side platforms for departing passengers only. The separation was enforced by access controls to the centre platform, location of ticket offices next to side platforms only, and opening trains' doors on the centre platform side first and on the side platform side with a delay. The separation was in operation until the 1980s.
