I've never gotten a Marklin product before since my layout's DC, but then after seeing one for a pretty good price, I thought, why not give a try at converting it to DC? A couple evenings of work later, and it turned out great!

Nice out of the box thinking. It took a bit of confidence to cut that core out of the field coil and replace it with magnets. Usually, getting those clearances around the armature right is pretty tough.

That thing to which he soldered the pickup wipers had once been the pickup from the center third rail. It looked a bit bent up, though.

Now how do you insulate one side of all axels on the Locomotive and tender to stop shorting out the power pack.

Thanks!
microbusss, the model does normally come with a large pickup shoe for the center contacts. It was missing from mine, but the spring was still there, so I flattened it out and soldered the new right rail pickup wipers to it.
toptrain, to prevent shorting and insulate the wheels, I reamed out the center hole with a round file before cleaning it out the rest of the way with a drill bit. Then I turned down pieces of plastic tube to fit in the larger hole and press onto the axle. This worked to insulate all wheels on one side. It takes some time and care to do it, but it's a lot cheaper than hunting down compatible insulated wheels.

Great video, very interesting conversion. I would be very interested in seeing how you would turn down those huge flanges. I wouldn't consider turning down flange wheels without a lathe or machine tool. However I have heard of modelers simply attaching a wheel set to a drill chuck and turning down the flanges on a common file, but this technique sounds imprecise and risky.
