What kind of freight train types can we see?
Can you give me more information about each type of freight train?
Boxcars are enclosed cars used for transporting a wide range of products, from consumer goods to raw materials. Tank cars are designed to transport liquids or gases, such as chemicals, oil, or propane. Flatcars have an open bed and are commonly used for transporting heavy machinery or containers. Hopper cars are used to transport dry materials, such as grain or sand. And intermodal cars are designed to carry shipping containers that can be transferred between trains, trucks, and ships.
