A ballast wagon is a type of railroad vehicle used for carrying and distributing track ballast, the crushed stone or gravel placed around and beneath railway sleepers. This ballast provides stability to the tracks, helps with drainage, and supports the weight of trains. The wagon is equipped with features that allow it to unload ballast evenly along the track as it moves. This process is crucial for maintaining track alignment and ensuring smooth train operations. Ballast wagons are commonly used during track construction and maintenance to keep the rail infrastructure in optimal condition.
