Why Do Rail Tracks Have Stones, But Metro Tracks Don’t?

Although both metro and railroad tracks are crucial for transportation, there are some significant distinctions between their design and construction. You’ve probably observed that, unlike metro lines, railroad tracks have stones strewn on them. This is due to a variety of technological and scientific factors (Why No Stones On Metro Tracks). In this article, tell us in detail.

On railroad tracks, stones, also known as ballast, are frequently seen. However, have you ever pondered why metro tracks are stone-free? Many people wonder why there is such a large discrepancy in the structure of the two tracks, given that they are both designed for trains. Understanding the design of railroad and metro tracks as well as how they operate is necessary to get the answer (Railway And Metro Tracks Difference). Tell us.

Why do railroad tracks have stones on them?

Stones are placed on railroad tracks for a variety of purposes. Let’s investigate.

Distribution of weight: Trains are heavy, and if they fall straight on the ground, the ground may sink. By creating a surface beneath the tracks, the stones lessen the pressure on the earth and evenly disperse the train’s weight.

Stability: The tracks are kept firmly in place by the stones. Vibrations are produced when trains move on the tracks. The tracks may become dislocated as a result of this vibration. The tracks are less likely to move because of the stones holding them together.

Drainage: Water can escape beneath rails thanks to stones. Water buildup beneath tracks can soften the ground and cause instability. The space created by stones allows water to escape, keeping the area surrounding the tracks dry.

Control of weeds: Stones keep weeds from spreading around the tracks. Weeds can harm railroad tracks and make it more difficult for trains to travel. Stones keep the tracks tidy by preventing weeds from growing.

Why don’t the metro tracks have any stones?

The lack of stones on the metro track can be attributed to a few factors. Let’s investigate.

Less weight: In general, metro trains weigh less than railroad trains. As a result, railroad tracks are heavier than metro lines. Because of this, fewer stones are needed on metro lines.

Urban locations: Due to limited land available, metro tracks are frequently constructed in urban areas. It might be challenging to lay stones in urban settings since they demand more space.

Maintenance: It is simple to keep metro tracks neat and clean. When stones are laid, dirt and debris may collect on the track, making track cleaning more challenging.

Construction: Metro lines are typically built with greater accuracy and sophisticated methods. Metro tracks are therefore more robust and sturdy than railroad tracks.
