The All-Russian Executive Committee of the Union of Railwaymen (Russian: Всероссийский исполнительный комитет железнодорожного профсоюза), commonly known in English by its Cyrillic acronym, Vikzhel, was the governing body of an industrial union established in revolutionary Russia during the summer of 1917. Inclined towards syndicalism and standing as one of the most radical Russian unions of the period, Vikzhel played a decisive role in stymying the attempted Kornilov coup in August 1917.
