This is a building set and a vehicle set at once. Sixty-seven blue, yellow and orange pieces interlock into track, and the supports raise it into ramps, bridges and a second storey, so the layout is different every time it is built. Two vehicles come with it — a white bullet railcar and a small black steam engine.

Nothing about the layout is fixed. The photographs show figure-eight loops, a raised yellow bridge crossing the lower track, and a red suspension bridge span standing over the whole thing. A child who wants a longer run pulls the layout apart and rebuilds it, which is the part that keeps a track set in use after the first week.

The pieces are chunky and hollow with peg holes down their length, closer to a construction block than a rail. They sit flat on the floor or on a rug, and because the sections press into each other rather than clipping over a lip, small hands manage them without help.

The box calls the set Magnetic Track, DIY Versatile Track Car, 67 pieces, strong suction. What a buyer needs to know is simpler: the pieces hold together well enough for a raised bridge to survive a car running over it, and they come apart when a child pulls them.

It suits three years and up. There is real problem-solving in it — a ramp that is too steep sends the railcar off at the bottom, and a child works that out by moving one support — which is why it lasts longer than a moulded track that only goes together one way.
