Not any kind of stone is suitable for use as ballast. The ballast used in the railway mainly consists of crushed stone, crushed slag, improved gravel, etc. Among them, the improved gravel is generally not used except for branch lines or station lines with minimal volume. The most widely used are broken rocks such as Igneous Rock and Hard Limestone.
