Which type of train is NOT considered a freight train?

The type of train that is not considered a freight train is one scheduled for passenger service. Passenger trains are specifically designed and utilized to transport people from one location to another rather than carrying goods or materials. This distinction is important because the operational procedures, design characteristics, and regulatory requirements for passenger and freight trains differ significantly.

Freight trains encompass various types of cargo, including bulk materials, hazardous materials, and agricultural products, all classified as freight because their primary purpose is to move goods rather than passengers. Understanding this classification helps in recognizing the specific roles and operations of different train types within the rail transport system.
