The coupler on one of my Lionel Heavyweights keeps opening randomly and inconsistently. It is a baggage car (made in 2010) or else I would just put it at the end of the train and forget about it.
I don't think that there is enough pressure on the coupler when it's supposed to be closed. I came to this conclusion because whenever I tap (not lift) the circled plate in the picture below, the coupler opens up.
Anyone have this happen before? Any solutions? I searched the forum and didn't see anyone with similar issues.
Thanks in advance!
