Abstract: A modular track for toy cars allows different race tracks to be made so that small toy cars can run along them. The track includes six types of pieces which combined according to the user's imagination provide multiple possibilities of different race tracks. Three of these types of pieces are stretches of the race track, straight, curved or sloped, which include some guardrails interrupted at the end to facilitate crossings and intersections in the race track. Two other types are connection blocks between the different stretches of the race track, and the other type is an end piece for the beginning and end of the race tracks. The connections between the stretches of the race track and the connection blocks are achieved by respective cylindrical holes and projections.
