To put slack in the cars, so when they pull forward, the loco's pull each car "one at a time" to assist starting. This is obviously done with heavy trains.
Trains by a mile
Trains carry automobiles in special cars designed to haul them. The cars are referred to as auto racks.
While trains give off more emissions than cars, they are actually more environmentally friendly than cars. This is because the train can carry very large groups of people, lowering the amount of vehicles are on the road.
Trains were first- 1784, but cars weren't invented until 1890.
Trains are better for the environment - as they produce less pollution per passenger than cars do.
