Abstract: A toy vehicle comprises a chassis having a front end, a rear end and first and second lateral sides extending between the ends. Two wheel trains are disposed on separate lateral sides of the chassis. Each train includes first, second, third and fourth wheels, a first pair of the wheels being mounted on separate axles fixed with respect to the chassis and a second pair of the wheels being mounted on separate axles movable along the first lateral side of the chassis. A separate continuous track extends about each wheel train so that the track engages over at least the first wheel and another other wheel. A separate linkage connects each second pair of wheels with the chassis and is configured to displace the second pair of wheels between a first wheel arrangement in which the wheels of the train are generally disposed in a single row, and a second wheel arrangement in which the wheels of the train are generally disposed in two rows and all the wheels engage the track.
