Railroad Workers' Day is observed in Russia, Belarus, and Kyrgyzstan on the first Sunday in August. This professional holiday was first established in the late 19th century to honor Emperor Nicholas I of Russia, who oversaw the construction of the country's first railways, including the 1838 line between Saint Petersburg and Tsarskoye Selo. Initially celebrated on June 25, the holiday was abolished in 1917 but was reinstated by the Soviet government in 1936 and later moved to its current date in 1940. The day celebrates the contributions of railroad workers, recognizing their vital role in transportation and logistics. While some former Soviet Republics altered or abolished the holiday after the dissolution of the USSR, Russia, Belarus, and Kyrgyzstan continue to commemorate Railroad Workers' Day each year.
