It is the Croation Railways version of “Pulling a Homer”. Weed killer and fire retardant was supposed to be applied to the ROW. Through corruption, the job was given to an unqualified boob — who not only failed to properly dilute the fire retardant, but also decided to mix it with the weed killer so as to save an additional weedkiller run. The slippery goop was applied to the rails just before a passenger train came through. It derailed, as did the following worker-train, which slid all the way down the hill with brakes locked.
