Why do trains go clickety clack?

The clickety-clack of a train rolling along a railroad is a familiar sound to many people. This unique sound is caused by train wheels passing over rail joints, which are used to hold sections of rail together. The joints are needed in locations where full welded rail is not possible.

We paint certain parts of the rail white so they absorb less heat – and expand less. Typically, a rail painted white is 5°C to 10°C cooler than one left unpainted.

At age 62, I could push a train car down a track. Unlike a steam engine that would hammer the rails (a main reason why they were retired), modern railcars glide with low friction, and crushed rock underneath the tracks helps diminish impact. You won't hear it or feel it, Rangel says.

Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.

Bells are most commonly used whenever a train is approaching a railroad crossing, grade crossing, or level crossing, as well as approaching a station, or moving at slow speeds. They're also used to alert crews and engineers of a departing train, which is used as a warning to move or board.
