Why are there rocks under the tracks?Ballast is a material such as crushed stone or gravel that is used to support and level the rails in the trackbed. The main purpose of ballast is to provide stability to the track, allowing for smooth and safe train travel. It also helps to remove water and other materials from the track. Without proper ballast, the track can become unstable and unsafe for trains to operate on.#interesting #unique #interestingfacts #facts #uniquefacts #technology #tech #education #science #sciencefacts @1001thacmac #1001thacmac
