How are railroad cars cleaned thoroughly enough to be used for different types of materials/liquids?
In: Engineering
This is all about chemistry. If you put the right washing agent in a rail car, you can dissolve whatever residue you want. Basically, you can spray the inside or fill it up with the solution and drain it. There are procedures for how to clean every chemical load.
Railroad cars are cleaned using a combination of high-pressure water jets, industrial detergents, and sometimes even steam cleaning to remove residues. Specialized facilities have equipment to handle various cleaning protocols based on the previous and next cargo. This ensures contaminants are thoroughly removed, making the cars safe for different materials and preventing cross-contamination.
