Ahmedabad Metro: Nowadays most people travel by metro. If you have ever traveled by metro, then you must have seen metro tracks. Small gravel or stones are not laid on these tracks like railway tracks, but why is this done, we will tell you in this article.
What is the special reason for stones on the railway track?
Let us tell you that the stones laid on the railway track are called ballast. When any train runs on its track, there is a loud noise and vibration on the track. Let us tell you that small stones are placed on the track to reduce this sound. There are two different types of layers on the track which are a soil layer and a normal soil layer. The lower strip of the track is called sleeper.
Let us tell you that an Indian train weighs about lakhs of kilos, which a track cannot handle. To handle the weight of such a heavy train, stones are placed on the sides of the iron track. These stones help in controlling the weight. Let us tell you that if stones are not laid on the track, then wild grass and trees will grow on the track, due to which the train will face a lot of problems in running on the track. Due to which there are also stones on the track.
Stones are not placed on metro tracks?
Let us tell you that the metro tracks are very busy due to which these tracks cannot be blocked. You must have noticed that some metro tracks are underground while some tracks are built above the ground. It is not possible to maintain the stone path at both these places.
Along with this, metro trains are coming almost every 5 minutes. In such a situation, blocking this track can cause trouble to people. This is why stones are not used on this track. Let us tell you that the cost of making a metro track is also a bit high.
