In 1837, the first railway built in Russia was a 6 ft (1,829 mm) gauge, 17 km long experimental line connecting
Saint Petersburg with
Tsarskoye Selo and
Pavlovsk. The choice of gauge was influenced by
Brunel's
Great Western Railway which used 7 ft (2,134 mm). The Tsarskoye Selo railway's success proved that a larger gauge could be viable for railways isolated from the extant 1,435 mm (4 ft 8+1⁄2 in) gauge Western European network.

In 1840, work started on the second railway in the
Russian Empire, the
Warsaw–Vienna railway in
Congress Poland. It was a 1,435 mm (4 ft 8+1⁄2 in)
standard gauge, with the express intention of allowing through-freight trains into
Austria-Hungary.

The modern Russian railway network solidified around the
Saint Petersburg–Moscow railway, built in 1842. There, the Tsar established a committee to recommend
technical standards for the building of Russia's first major railway. The team included devotees of
Franz Anton von Gerstner, who pushed to continue the Tsarskoye Selo gauge, and engineer
Pavel Melnikov and his consultant
George Washington Whistler, a prominent American railway engineer. Whistler recommended 5 ft (1,524 mm) on the basis that it was cheaper to construct than 6 ft (1,829 mm) and cheaper to maintain than 1,435 mm (4 ft 8+1⁄2 in). His advice won over the Tsar.

At the time, questions of continuity with the European network did not arise. By the time difficulties arose in connecting the Prussian railroads to the Russian ones in Warsaw in the 1850s, it was too late to change.

A persistent myth holds that
Imperial Russia chose a gauge broader than standard gauge for military reasons, namely to prevent potential invaders from using the rail system.
[8] The Russian military recognized as early as 1841 that operations to disrupt railway track did not depend on the gauge, and should instead focus on destroying
bridges and
tunnels.
[6][7] However, in both World Wars the
break of gauge did pose some amount of obstacle to the invading Germans.
