Echelon Song
The Echelon Song, also known as Song for Voroshilov or Battle of the Red Guards, is a Russian song written in 1933 by A. V. Alexandrov and Osip Kolychev, dedicated to Kliment Voroshilov.
It is one of a number of popular Soviet songs which reminiscence about the Russian Civil War era.
This particular song is about the "railway warfare" during the Battle for Tsaritsyn of 1918, where Voroshilov and Joseph Stalin became friends. The music of the song is composed so as to recall a steam locomotive, beginning in an accelerando and crescendo, and ending in a decrescendo.
The song has been used for the closing credits of the 2016 film Hail, Caesar!
