There are many different types of freight train, used for carrying a huge variety of different kinds of freight, with various types of wagon. One of the most common types on modern railways are intermodal (container) trains, where the containers can be lifted on and off the train by cranes and loaded off or onto trucks or ships. In the US, this type of freight train has largely superseded the traditional boxcar (wagon-load) type of freight train, which requires the cargo to be loaded or unloaded manually. In Europe the sliding wall wagon has taken over from the ordinary covered goods wagon.
