Question

What is the difference between body and truck mounted couplers?

Answer 1

Trains in Europe have chains mounted on the body and need buffers to keep them apart.

In the US trains have knucle cuplers which hold the carages together and keep them apart.

Answer 2

You have to be talking about toy trains here...

I don't know any real trains with truck mounted couplers except maybe the old TALGO sets.

Real trains have the coupler in a coupler pocket mounted on the body of the car...

On a toy train, a truck mounted coupler is mounted on a pocket attached to the bolster of the truck to allow for tight radius curves on layouts.

Answer 3

well, I imagine one is mounted on the body of the car and one is mounted on the truck (axle/wheel/suspension thinger).
