The Kadee #321 allows operators to uncouple rolling stock without touching the models. Its delayed uncoupling feature makes complex shunting manoeuvres and wagon placement more realistic while reducing handling of locomotives and rolling stock.
How to use it
Install the uncoupler between the rails at the desired location following Kadee's installation instructions. Position Kadee-equipped couplers over the magnet to activate the delayed uncoupling feature during switching operations.
