Warsaw–Terespol railway

Four years later a bridge was built across the Bug river along with a 5 kilometres (3.1 mi) long line linking Terespol with Brest-Litovsk (Polish: Brześć Litewski, today Bierascie in Belarus), in the part of Poland annexed by Russia earlier in the Third Partition of Poland, thus connecting the railroad with an existing line running to Moscow.

The line did not reach Warsaw proper, instead ending in the borough Praga on the right bank of the Vistula river, as the time the occupation authorities for strategic purposes blocked the construction of heavy railway bridges across the river.

After World War I started in 1914 the line was largely heavily damaged by the retreating Russians and later partly restored and converted to standard gauge by occupying Germans for military use.

The rest of the line to Terespol, where the post World War II border between Poland and the Soviet Union was set, was electrified in the 1970s.

In the 2000s the entire line was modernized, allowing conventional passenger rail at speed of 160 km/h and heavy freight at 120 km/h.
