As a result of collision between passenger and freight trains, 25 people died and 8 survivors were injured. Accident The crash occurred on a single stretch of line because track maintenance work was being carried out on a second track.

EN57, travelling at 30 mph (50 km/h) collided head-on with the double-headed ironstone-transporting freight train approaching from Pilawa, hauled by an ET41-series electric locomotive. The first coach of EN57 was completely destroyed by the force of the collision. Sources J. Reszka, "Cześć, giniemy! Największe katastrofy w powojennej Polsce", wyd.
