Hi,

I bought a brand new Z scale 88190 Santa Fe train a few weeks ago.
http://www.maerklin.com/...Fdiesel_locomotives.html

But only one motor was running, so it was back to the shop.

Today I picked it up after being repaired, and now both motors are running.

But they don't run equally. The motor in one end of the train starts running as soon as I give it just a little power, but the other motor dosn't start until I reach about 100-120 (out of 200) on the controller. And this also means, the train dosn't start moving, until I reach about 120.
It's always the same motor that starts late, no matter what direction I drive.

I this a fail or a feature? Is a A-B-A design supposed to work like this?

And I can only put about 5 cars on it, then it barely drives anymore, unless I give it full power.

So I'm feeling that all my 20-25 years old trains, that I inherited from my grandfather, runs much better than this brand new one that I bought.

Thanks for your reply.

I'll test it a bit more, and then probably take it back to the shop.

Thanks for your reply.

I'll try to let it run some more, and maybe a drop of oil, and see if it improves.

Thanks for the link, I'll take a look at that forum.

Jens, it is probably something with the gears. Take a look at this site: http://www.zscale.org/articles/revival.html
