Yes — the wheel sets grip both edges of the ladder-style track, so the engine stays attached through the full 360-degree loop, even at the very top.
No tools are needed: the track segments simply snap together and bend into shape, and most kids enjoy doing the building themselves. It packs back into a compact box for storage.
The engine is battery-powered and drives the motion, headlight and sounds. The listing doesn't specify the battery type, so check the package before gifting.
Based on the product details, the set is aimed at ages 3 and up — the pieces are chunky, snap together without tools, and no reading is needed to play.
