Trains stay on tracks because they have special wheels that hug the rails! 🚂 The wheels are shaped like a big letter "U" and fit perfectly on the metal tracks. This helps the train stay in place and not fall off.
Also, the tracks are very strong and flat, so the train can roll smoothly without wobbling. 🛤️
Trains stay on tracks thanks to a clever design of their wheels and rails! 🚂 The wheels have a flange (a raised edge) on the inside that keeps them from slipping off. The rails are also slightly tilted inward to help guide the train.
Another trick is that trains are very heavy, so gravity pushes them down onto the tracks. Engineers make sure the tracks are strong and straight so trains can zoom safely! 🛤️⚡
Trains stay on tracks due to a combination of physics and engineering! 🚂 Here’s how it works:
Train wheels have a tapered (cone-shaped) profile and a flange on the inner side. The taper helps the train steer slightly around curves, while the flange acts as a safety guard to prevent derailment.
Rails are slightly inclined inward (called cant), which helps distribute the train’s weight evenly and reduces wear. The tracks are also welded or bolted together to minimize gaps.
The heavy weight of the train increases friction between the wheels and rails, preventing slipping. Engineers also calculate the perfect balance between speed and track curvature for safety.
Modern trains even use sensors to detect track issues! 🛠️
