Abstract: Large amounts of hazardous goods, especially liquid ones such as fuel, may be carried in safety containers, whether tank semitrailers, oil tankers, containers for hazardous goods or aircraft, and be transported with practically no risk for the environment, by completely filling the inside (10) of the container with glass wool, so that the hazardous materials or other fillings dispersed therein may not escape or be somehow spilled in the environment. The liquid components, for example hydrocarbons, are absorbed and held by a dense, water-proofed latticework (15), so that no oxygen can reach them. They are thus protected against explosions and spillage in the environment. At the same time, a safety container of this type acts as a kind of safety buoy, preventing water from entering the inside (10) of the container, so that the kerosene, gasoline or oil contained therein further increase buoyancy. As a whole, a simplification of the safety container design and a considerable increase in safety may be noted.

A hoist on the truck moves the sand container from the truck to a location adjacent the locomotive to allow sand to flow into a sand hopper on the locomotive.
