Explanation:
A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars.[1] Rail freight practices and economics vary by country and region.
If you have ever been near a train when it starts to move, you see (and hear) something interesting. The engine car at the front starts to move and in doing so, you get this wave of compressing couplings between all the cars.
