Rail spike

Okay kiddo, have you ever seen train tracks before? They are made of long pieces of metal called rails that are connected together to make a path for trains to drive on. But how do those rails stay in place and not move around when a train goes over them? That's where the rail spike comes in!

A rail spike is a small but very important metal nail that is hammered into the wooden ties (which are like big blocks of wood) underneath the rails. They hold the rails in place and keep them from shifting around when a train goes over them.

Imagine a really big puzzle where each rail spike is like a little piece that connects the different parts together. Without those spikes, the puzzle pieces (or the rails) would move around and the train wouldn't be able to stay on the tracks.

So, rail spikes are super important for keeping trains safe and on track!
