Why are train tracks always on gravel?
Why are train tracks always on gravel? Railroad ballast is a crucial component of the rail transportation system. It is a crushed stone or gravel material that is used to support and level the tracks in a railroad track bed. The primary purpose of ballast is to provide stability to the tracks, allowing trains to run smoothly and safely.
Why train engines are not switched off?
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
How many trains derail per year?

Why do train tracks buckle even with gaps?
Because rails are made from steel, they expand as they get hotter, and can start to curve this is known as 'buckling'. Most of the network can operate when track temperatures heat up to 46°C – roughly equivalent to air temperature of around 30°C – but rails have been recorded at temperatures as high as 51°C.
How do train tracks not break?
