On July 31, an echelon with military equipment and ammunition for the occupiers arrived at the "Kalanchak" railway station of the Kherson region. At 8 a.m. the next day, the Russians began unloading the echelon. Apparently, in order to mask the unloading process and protect against HIMARS strikes, the occupiers used powerful means of smoke. At approximately 11:20 an explosion rang out in the work area. It was not possible to accurately determine its nature due to a thick smoke screen. However, immediately after the explosion, the echelon without any warning started moving in the direction of Crimea. The enemy's personnel scattered in panic.

Presumably, the explosion resulted from careless handling of ammunition during unloading or a fire that arose due to inept use of pyrotechnics during the creation of a smoke screen.

Also, on July 29-30, the Ukrainian military hit the Russian railway echelon that arrived at the Brylivka station. The echelon consisted of more than 40 wagons with manpower, equipment and ammunition.
