How do trains join?


How do trains join? A modern freight train can include more than one-hundred cars and be over a mile long. Couplers hold the cars together, from the first tug of the engine, as its force overcomes the inertia of each car, to the end of the train.


How do trains communicate with each other?

Most signalling systems use trackside signals to control the safe movement of trains and tell drivers what to do. A colour light signal shows different colours to authorise train movements.


Why do train wheels not slip?

To help the wheels stay on the track their shape is usually slightly conical. This means that the inside of the wheel has a larger circumference than the outside of the wheel. (They also have a flange, or raised edge, on the inner side to prevent the train from falling off the tracks.)


Do trains wait for connecting trains?

Yes to a point Factors they have to consider include delays to passengers already on a train that has to wait, the potential to miss other connections, what the alternative connections are, and other consequences of waiting.
