I tried it and that's what made me go to Kato Unitrack. It was OK but I had a lot of trouble with the turnouts. Clearances weren't matching and I had derailments...lots of derailments!
Here is a tip from Modelrailroader magazine:

In case anyone is looking for track I have a bunch up for sale on ebay.

Boy did I way over buy!
First thing I do after a careful visual inspection is to take the cover off and put current directly to the motor. That way you know if it's just dirty wheels or a wire needs to be soldered or something like that.
