Janney coupler

Okay kiddo, so you know when you play with your toy train and you want to connect two trains together? You usually do that by just pushing them together, right?

Well, real trains also need to connect to each other to work together and move along the tracks. That's where the Janney Coupler comes in.

It's a special kind of mechanism that helps two train cars connect to each other easily and safely. The Janney Coupler has two parts: a knuckle and a socket.

The knuckle is a curved piece of metal that fits into the socket of the other train car. When the two train cars are pushed together, the knuckle automatically locks into place in the socket.

This is really important because it helps the train cars stay connected, even when they're moving really fast. And since the Janney Coupler is standardized, it means that any train car can connect to any other train car, no matter the type or brand.

So that's how the Janney Coupler works in a nutshell. It's like a special lock that helps train cars stay connected safely and easily. Pretty cool, huh?
