Freight systems refer to the methods and processes used to transport goods from one location to another. These systems can include various modes of transportation, such as trucks, trains, ships, and airplanes. Each mode has its advantages, like speed or cost-effectiveness, and is chosen based on the type of cargo and distance involved. Efficient freight systems are crucial for global trade and supply chains, ensuring that products reach consumers in a timely manner. They often involve logistics companies that manage the movement of goods, including warehousing, packaging, and distribution to optimize the entire shipping process.
