Lyrics:

Echelon after echelon,
Echelon after echelon:
The road begins to widen.
The commander orders to point!
Waving a small white handkerchief
To the Don’s blue hand.
 
Voroshilov, you’re with us,
Hiking through life, we became friends,
Together we flew into battle:
Remembering the enemies with longing
Fighting for the white Kalitva,
Fighting for Kalach station.
 
For the Tsaritsyn, for the Tsaritsyn
We’ll fight through day and night,
Crossing peak after peak:
Don’t wash it away with the rain,
Don’t blow it away with the wind -
The blood of the peasants and the workers!
 
The commander orders point!
Waving a small white handkerchief
To the Don’s blue hand.
Echelon after echelon,
Echelon after echelon,
The road begins to widen.

I feel like the song’s rhythm and the instrumentals fit the lyrics perfectly. You can really hear the locomotives and how they speed up towards the end of the song.
