Have you ever wondered why many pebbles are on the railroad tracks? Apparently, this pebble has its own function. According to the Head of Public Relations Daops I PT KAI Edi Kuswoyo, pebble has a function as a ballast that helps the rails remain stable and dampen vibration.

Reported from the page Kompas, in addition, the stone krikil is to prevent the growth of wild plants that can cause the land under the rail is not stable.

"If there is a plant, it can disrupt the structure of the railway line, as well as to keep the rails in place when the train passes through the rail," said Edi, Wednesday (14/3/2010).

He also said, the mention of krikil is not really right. The stones on the track, he said, are called ballasts. "The mention of pebbles is not very precise, the truth is the ballast, exactly kricak ballast size 2/6 centimeters," he said.

The ballast is part of the railroad body where to put rail pads. The placement is between, below, and around the hinggadrainase lane on the right-hand rail.

The ballast on the tracks is made up of two layers. The first layer consists of crushed stone and angular. The second layer or subbalast usually contain coarse sand, medium pebbles, or fine pebbles.

For the treatment, be done regularly by cleaning the ballast layer of mud and dust. This treatment is also to keep the ballast density and sometimes if necessary the ballast is replaced with a new layer. (Source: Compass)
