I have the older Roco Atlas and the newer China Atlas switchers. The China one never ran well or pulled more than several cars without spinning its wheels. I found that it was only getting power to the front truck. While checking the wiring connection found that the screws that hold the board with the led on it were loose. After retightening them it now runs and pulls as well as the older Roco engine. Maybe this is the case with yours. By the way if you look on the bottom of the chassis it will say either made in China or made in Austria(Roco)
