Later on, plans were changed, with the connection shortened to one between Okęcie and Warsaw West railway station.

Plans were shortened once again, with the final draft of the line covering stations from the National Stadium to Gocław.

In 2015, Warsaw city authorities planned for the construction of the M3 metro line between Stadion Narodowy and Gocław to commence in 2020.

The technical study would analyse the proposed route and the preferred location of stations of the first section of the metro line between Stadion Narodowy and Gocław.
