Eddie asks:

“I’ve got several Kato cars that are causing no end of trouble to couple and uncouple. Admittedly they are N scale so are small and fiddly. Removing them from the track is the easiest way to uncouple them, but putting them back on the track when coupled is tricky. I see there are several brands online… if I replace my Kato couplers which brand would work best?”
