Hey Guys,

I have a brand new set of MTH Western Maryland 2 Bay Coal Hoppers that I am pulling behind my Lionel Legacy CSX Dash 9 that are uncoupling radomly. It seems to happen more running at Limited Speed, and happens quite often at Normal Speed. I looked at the cars as they went around the track and they don't seem to be bouncing a whole lot. After the last few releases I looked and the coupler was actually in the release position. It was not closed like it had just hopped out from the other car. Is this a defect in the car, or is it just a case of a bad coupler? I would chalk it up to a bad coupler, but it seems to be random as to which car disconnects. It is not the same car each time. Thanks guys!

Tom

I have a Railking passenger car that had the same problem.  I took it back to the shop where I bought it and the owner showed me how to fix it.  There is a pin on the pull down arm that sticks into the knuckle and prevents or allows uncoupling.  He carefully bent the pin ever so slightly towards the wheels and that did the trick

out of the 7 or 8 premier freight cars i've purchased over the past year , there were 4 that have uncoupling issues. i had to take a screwdriver to push outward on the coupler shank( really hard to explain here). you want to be careful when you apply pressure against the carbody doing this. so far i've been able to get 3  cars fixed so they stay coupled up as intended.

on this past years production,some thing changed the way the trucks were made. i dont know if the railking cars ' trucks use that flat plate on the bottom. im a 100% premier guy.
