Method and database arrangement for inspection and requalification of vehicles used for transporting commodities and/or hazardous materials

This invention describes a computerized method for managing the inspection and requalification of tank cars used for transporting goods. It involves inspecting a tank car, inputting the inspection results into a computer system, and then having the computer combine this data with other information like ownership or commodity type. Based on this combined data, the computer calculates a new requalification date for the tank car, which can then be displayed, printed, or even directly imprinted onto the car's surface.
