Track geometry

Track geometry is like the shape of a rollercoaster that trains ride on. It's like a big puzzle where engineers decide how high and low the track should be so trains don't go too fast or slow, or tip over.

They use math and measurements to figure out how steep a hill should be, and how curvy the track should be. They also make sure there are no bumps or dips in the track that could make the train shake or bounce around.

Imagine playing with a toy train set and trying to build the perfect track so the train can go smoothly without falling off. That's what engineers do with real train tracks, but on a much bigger scale. They make sure trains can travel safely and smoothly from one place to another.
