gauge Warsaw and Vienna Line had been the first long-distance railway under Russian rule at all. Saint Petersburg–Warsaw Railway Warsaw's first link to the system was the Saint Petersburg–Warsaw Railway, completed in 1862. One year before, a branch of the line had reached the Russian and Prussian border with Verzhbolovo Station in Kybartai. This first junction of Russian wide gauge and Prussian standard gauge networks passed the northeastern corner of Russian Poland, which did not become part of Poland again after Polish revival. Warsaw and Bydgoszcz Railway Also in 1862, the last standard gauge main railway line in Russian Poland was opened between Łowicz (at a branch of the Warsaw and Vienna Line) to Aleksandrów Kujawski near the Prussian border. It was the Russian part of the Warsaw and Bydgoszcz Railway, the first direct connection between Warsaw and the Prussian ruled parts of old Poland. Warsaw-Terespol Railway In 1866, the direct railway form Moscow to Warsaw via Brest was finished. Iwanogrodzko–Dąbrowska Railway Later, another wide gauge railway track was added: the Iwanogrodzko–Dąbrowska Railway from Dęblin via Radom–Bzin (now Skarżysko-Kamienna)–Kielce–Tunnel to Dąbrowa (now Dąbrowa Górnicza Strzemieszyce) and from Ostrowiec Świętokrzyski to Łódź via Bzin–Tomaszów Mazowiecki–Koluszki. This caused a temporary decrease of cargo transport (mainly coal) on the Warszawa–Vienna Railway. The Russian General Staff confirmed the exclusive production of wide gauge equipment in the territory of Russia. Wrocław–Warsaw Railway The Russian authorities refused extension of the Wrocław–Warsaw Railway (Oleśnica–Podzamcze) to Łódź and Warsaw on their territory. The Engineering Railway School in Warsaw was opened under the line's protection in 1873. Ring Railway (Kolej Obwodowa) In 1875, Warsaw's first railway bridge across Vistula river was opened (Gdański Bridge – former Ring Railway Bridge), connecting the wide gauge lines east of the river to the standard gauge lines starting from Vienna Station in the west. Ring Railway (Kolej Obwodowa), in 1876, connected the Warsaw-Vienna and Warsaw-Terespol Railways Other In 1888, all railroads in Russia were nationalized. The revolution of 1905 in Russia and Congress Poland led to the disorder of the rail traffic on many important routes and many important junctions. However, after the revolutionary events, the traffic was restored and many new technical improvements were implemented, especially for military sake. World War I Soon after occupying Polish areas, the German railway army readjusted the railway from Russian (broad gauge) to . On the Russian side, most of the rolling stock of the Warsaw–Vienna
