I purchased a 3 rail Marklin 3071 set to convert to a 2 rail dc set. Using an old 1993 magazine article as the guide for the conversion I have been able to rewire the locomotive and 3 trailing cars. Added wheel wiper pickups to the metal trucks to supply power to the loco and upgraded to directional led white and red lights. Coaches also led equipped.
Only problem is the part numbers for the dc wheels are now 16 years old and hard to source. To the best of my ability I purchased new dc wheels which fit pretty well until I was ready to test run on the track. I’m having the cars derail often and the locomotive drive wheels although functional, they’re less then ideal.
So my question to the Marklin community is
1-how can I find Marklin dc wheelsets for the 3071 model.
2- if it is in a Marklin catalog, can someone direct me to where I can reference it, or possibly share the part number so I can find some
3- what would the wheel specifications be for the coach consists and for the locomotive so I can try to find alternative options.
Thanks

You can check with Ritter Restaurationen, APC Modellbau, amiba-shop.ch and other shops that offer parts/repairs to see if they have the parts.
I wonder though, why you decided to convert an AC model rather than sourcing a Hamo model, which are usually available on sites for the same price as the AC models or less.

My apologies for not foruming properly. I’m quite new at customizing ho scale locomotives and rolling stock and don’t often reach out to the online community.
Some backstory-
I picked the red and taupe three rail 7030 AC version of the TEE train because I enjoy fixing older cast away models and giving them new life. Also the Northlander TEE trainset is not very common here in northern Ontario Canada and when one is found they are quite expensive. Especially the new DCC models. So I jumped at the opportunity at a local train show and bought the set at a good price.

I figure I’m a good 90% done the restoration/kitbash process on this set.
The problem I have been having are that passenger cars derail as they enter a turn and the locomotive Weelsets have a bit of a wobble to them (I did a no no and drilled the locomotive wheels slightly larger for plastic inserts on my drill press). In hindsight it is clearly not accurate enough. Lesson learned.

I think the derail problem may be caused by the flange on the new DC wheels not being tall enough and the coaches are too light to keep it on track. The radius is about 22” on code 100 track.
But I think I have just found a supplier of dc 36”wheels. Using digital callipers, the measurements to the old AC wheels are almost spot on. I’ll know once they are delivered to me. See the attached spec pic.

So that now leaves me with the 40” locomotive wheel sets to figure out.
I have googled the dc version mentioned above in response with no real leads for wheelsets. Nothing on ebay as well. Seems a dead end for now.
The original magazine recommended
NorthWest Short Line wheelsets which were discontinued. So after reaching out to NWSL they gave me new numbers. Part no 37131-4 , 40"/110 Shldr 2mm x 1.025" axle & 37118-4 Wheelset, HO 36"/110 Pointed 2mm x 1.015" axle. Only problem is I can only find them from the USA and after currency conversion and shipping it is way to expensive. So for now not an option.
So at the moment that’s where I’m stuck.
Was hoping someone with more experience and more knowledge might have another solution for other wheelsets or Canadian wheelset supplier suggestions to solve the my wheel problem.
Thanks
