At its peak the lines of the Warsaw Railway Junction served approximately 250,000 passengers daily[citation needed].
In 1862 the Warsaw-Saint Petersburg Railway was opened connecting Warsaw through Vilnius (Wilno) with the Russian capital followed by the Warsaw–Terespol Railway in 1866, both lines were built to the Russian broad gauge and only reached the city's eastern part on the right bank of Vistula River, known as Praga, as the occupational authorities blocked the construction of a railway bridge across the river for strategic reasons, only allowing the rail terminals to be connected by a horse tram.
In 1877 the Vistula River Railroad was built as the third broad gauge line on the right bank in Warsaw linking the city with Kovel and with the border of Polish territories under Prussian control in East Prussia.
In 1902 the broad gauge Warsaw–Kalisz Railway was constructed on the left bank of the Vistula river connecting Warsaw through Łódź to Kalisz and later extended to the border of the Prussian controlled Province of Posen.
In 1934 a new railway line was opened connecting Warsaw with Radom and further with Kraków finalizing the present day track layout.
