End-of-train device

An end-of-train device is a little helper that sits at the back of a train and helps keep everyone safe. It's like a guard that makes sure the train doesn't do anything it's not supposed to.

So, let's say you're on a train, and it starts moving. You might not be able to see what's going on behind you, but the end-of-train device knows everything! It uses special sensors to measure how fast the train is going, how long it is, and if anything is blocking the tracks.

If the end-of-train device thinks something is wrong, it sends a message to the train driver to let them know. But it can also do more than that! It has special lights that flash to tell other trains that this train is coming, and it can even apply the brakes if the train needs to stop really quickly.

The end-of-train device is like a superhero for trains, making sure everyone stays safe and that the train works properly. Without it, trains wouldn't be able to go very far, and it would be much more dangerous to ride on them.
