Unveiling Model Train Couplers: How They Connect And Pull Cars

Discover the ins and outs of model train couplers and how they work. From connecting train cars to pulling them along, get the scoop on these essential components.


What Are Model Train Couplers

Model Train Couplers are small devices that connect and hold the train together while the train is moving.


Two Main Jobs of Model Train Couplers


A.) Connect the train cars


B.) Pull the train cars as the model train moves


So, How Do Train Couplers Work?

The engine or locomotive has the motor built into the car. (The first train car in formation.) So, when the engines move forward or backward the train cars move because of the force connected to the engine while the couplers hold it together. 


Real Life Example:

Let's say you are at the lake to go waterskiing. The boat has an engine. The boat has a cord attached to it to pull the skier. So the skier who holds the cord gets pulled forward by the boat. So, in this example, the cord and hands of the skier are the couplers. The skier represents a train car. The boat represents the train engine or locomotive car.    


What are the Two most common Styles of Model Train Coupers?

The two most common styles of model train couplers are Knuckle couplers and Horn Hook couplers.


Conductor Pro Tip For Couplers

Make sure the Model Train you are running has all the same style of Coupers. The different styles of couplers are incompatible with each other.
