Bert Send it back for a refund. It is not what you required when you bought it so why pay for it. If you dont complain and get your hard earned cash back then Marklin and the dealer think you are satisfied.

Your best bet with the coaches is probably to disassemble the offending parts and trim away the flash. The loco may be harder. First, check the back to back measurements on the jammed wheels (they may have been pushed too far onto the axles). Failing that, check for any flash. It really does sound like a case of a fraction of a millimetre making the difference.

I think that Matt is right about wrong positioning of the wheels on that axle. Are there any sideplay at all of the wheels with regard to the outer tracks when the loco is resting on the track?
The inside (back to back) measurement between the wheels must be 13.9 mm.
If that is ok, the axle (wheels) must be touching something on the base of the loco when it is resting on the track.

I have the set and it runs well with no problems. I'll look at me set to possibly see how to address you problems.

Sounds like a good way to identify the issue, unfortunately, all my trains are left in the Netherlands whereas I'm staying in Sweden for at least 4 more months. Won't be able to help in this matter. Sorry.

Hi all, thanks for your replies,

Checked the issue again this morning before going to work after reading your replies. The bogey seems to be inserted normally, so no inversion a la BR05.

There is a spring present under the bogey and the pressure appears ok, I think if it would press a lot harder it would maybe lift the traction tires from the rails.

The thing I did notice after I removed the wheels from the bogey is that they have a 'fat' metal part in the middle that just fits between the plastic clips. On the clips there is some molding 'flash' (Is this the correct term then?) that seems create additional friction on the sides of that fat part. Tonight (if I have the time) I will try to remove it with a sharp knife. I will also try to take some pictures.

Benny, I think you are right it is a plain mechanical problem. Would be much happier though if it worked right out of the box.

About the cars, I wonder whether it'll help to some oil on the shifting part of the middle axle, or if I'll do more bad with that than good. Once applied it will be very difficult to remove the oil again.

That moulding flash is most likely the cause of the problem - certainly it sounded as though the wheels could turn, just not as freely as they need to.

Flash is the word we use here, not sure about the rest of the world. It's caused when plastic seeps between the segments of a mould and is usually seen on worn tooling. Some kits that have been in production for some time are covered in the stuff!
