It is your decision as the user what is an appropriate load for the pins, many factors could come into play which may affect their strength. For heavy trains, you may wish to use a thicker bar/pin. 

Couplings should always be used in conjunction with a locking pin and safety chain, in accordance with relevant guidance. For more info on miniature train operation please look at our Safety page.
