An electric motor driven toy train is disclosed which has a novel wheel and track assembly for minimizing slippage and avoiding binding between the train's wheels and the track as the train goes around a curve section of the track. The train's wheels are each stepped in cross-section with a small diameter rim and a large diameter rim, and the wheels ride on track sections with rails that are also stepped in cross-section. The inside rail of a curve track section is structured so that only the inside train wheels' small diameter rims ride thereover, and the outside rail is structured so that only the outside wheels' large diameter rims ride thereover. The train comprises multiple cars, each of which is articulated about a vertical axis and each of which has only a single axle so as to minimize the turning radius of the train set. A child sits upon the second car, the coal tender, and steers the first car, the locomotive of the set. A small battery driven electric motor drives one wheel of the tender to impart motion to the train set.
