Hello, tried to do a search for this issue but looks like it was never brought up. The Marklin couplers on the longer passenger cars tend to sag a bit. The bottom decoupler vertical pin piece sometimes fouls on the silver part of the turnouts causing the passenger car to stop, mostly at low speeds. I think at higher speeds it's able to power through them. I've looked at potential fixes and narrowed it down, any ideas? 1) file down and lower the metal silver piece in the middle of the turnout 2) cut off the grey plastic curved pieces embedded in the track 3) cut off the Marklin coupler pin
I would cut off the coupler pin unless you're using a Marklin uncoupler track ..... which I suspect you're not if you're using all Rokuhan track.
Never seen one droop that low. From the looks of the roof in both pix, I suspect from high temperature exposure. But cutting off the pin solves that issue. But the coupler sag needs to be checked against other cars. It might just be that one.
That roofline is typical of a European passenger car. One other option is to remove the truck and swap it with a better truck on the back of the car you have at the end of the train.
It may just be the picture angle making it look worse but that was the worst offender. So it's been relegated to storage bin status. Others are droopy but not enough to catch the turnout....yet. Anyways cutting off the pin is the way to go. I only got these for $10 each so no big deal.
I have seen couplers droop, but this one is pretty low. Check the coupler box plate and make sure it is secure. If these are loose, it can cause the coupler to hang low. If it is okay, then file the pin slightly. If you aren't planning on using the auto uncoupling, the pin is not so important.
