I have the LGB Stainza (I think I spelt that wrong)from the #92400 set. It seems like I get a buildup of black, oil on the track. Seems like I have to wipe the track all the time so the train runs smooth. It also seems to run better backwards than forward. It also slips a lot and studders at times mainly going forward. When I clean the track it is fine for a little bit. Anything I can do to prvent this. My guess is the oil comes from the engine but not sure where. My Big Hauler left the black oil on the track but not nearly as bad and it does not slip, just slowes it down some. Anything I can do to help it out.
The black goo on the track is from plastic wheels on your rolling stock. If you already have metal wheels on your cars, my apologies. If you don’t, get some!
A second cause could be arcing between the track and the loco wheels. Different metal wheels do it more than others. I use a couple of drops of CRC 2-26 on the pad of my track cleaning car (found in the electric aisle of the home box store). It helps cut down on it quite a bit. If you run in the dark at night you can see the arcing.

Being in NJ you would not experience heat wave conditions, but we in the sub-tropics do, and the hot rails will actually melt plastic off the plastic wheels, so the first thing I do with any new rolling stock is put metal wheels on, they run better, make a nick clicky noise on rail joints, and do not melt onto the rail head. Thankfully Bachmann rolling stock only come with metal wheels fitted.
I went out and picked up some of that CRC 2-6 (spray form) I spayed some on a scotch brit pad and what a difference. It runs fast again. Like new. Its nice because it acts as a cleaner plus it gives it more conductivity. At first I though it makes the track a little slippery and with the lightweight of the stainza I have thougt it would slip more. I guess it helps make the contact shoes on the engine slid rather then drag. Thanks for tip.
