Russian railway workers celebrate their holidays on Sunday. The story of the railway workers' holiday dates back to July 25, 1896. The holiday celebrated on the birthday of Emperor Nicholas I, who initiated the railway construction in Russia, is the first professional workers' holiday celebrated both in the Russian Empire and in Europe. The festival, which was carried to the first Sunday of August after the 1917 Revolution, had not lost anything of its scope and color. So much so that during the Railway Workers' festival, orchestras give concerts in all major stations of the country, senior workers and pioneers are honored and new transportation points are put into service in different regions.
