Made for little days

Two obsessions, one set
For the kid who loves trains and building: they snap the track together, then switch on the train and watch it run the loop they made.

Exactly what's in the box
51 pieces: track and connectors, 1 train, signs, rods, bases and a USB cable. Some photos show several sets combined; one set builds the loop on the box.

Fresh layouts, same set
Twist the connectors apart and rebuild a new shape. Same pieces, a different track, and no new toy needed.

No battery runs
Charges by USB, so no stash of spare batteries.
