I just received a brand new Lionel B60 baggage car I ordered in the mail today, and the couplers seem to open on their own when a train is running.
Usually this means a faulty spring, but the spring seem fine to me. when I close the coupler and fiddle around with it myself, I can't seem to get it to open, yet it will at random while a train is running. Note I also do not have any uncoupling tracks on my layout.
Does anyone else have this issue? I'd be pretty disappointed if this is a common problem with a plastic piece of rolling stock Lionel wants to charge $160 for.
