Description

A physical way to think in steps

Rather than relying on a screen, this set turns sequencing into something you can hold: large Duplo bricks click together easily, which suits small hands well. At 235 pieces, Coding Express sits in the mid-size range for Duplo sets, giving enough variety to lay out different track shapes. The set includes a locomotive, several carriages and track sections that can be rearranged freely. With no minifigures included, the build stays focused on the train itself and on how each action brick — forward, left or right — changes the order of movement along the track.

White, grey, yellow and red

The main colours are white, light bluish grey, yellow and red, a bright and high-contrast combination that makes pieces easy to tell apart for younger builders. With 110 unique parts, the set offers a fair amount of variety without becoming overwhelming, which fits the age group it targets. The oversized Duplo shape makes track pieces, connectors and action bricks easy to distinguish by touch as well as by sight. If a piece from the set has gone missing, the full parts list on this page makes it straightforward to check exactly what belongs.

Built for repeat play

Because the track can be rearranged in countless ways, Coding Express is designed for repeated play rather than a single build. It also mixes well with other Duplo sets, since rail sections and carriages tend to share connection points across the range. Parents or older siblings can use the layout to introduce basic ideas about sequence and direction long before any screen-based coding is involved. For anyone tracking down a specific piece or combining it with other Duplo sets, the full list of all 110 parts is available above.

A set that grows with a household

As a gift for a preschool-age child, Coding Express holds up well over time: the oversized Duplo pieces are sturdy enough to survive several rounds of play within the same household and connect easily with older or newer Duplo sets already on hand. Because no small loose parts can render the whole set unusable if lost, the track stays playable for years rather than becoming incomplete after a few sessions. For parents looking for screen-free, early-learning play specifically, Coding Express offers a durable starting point that can keep growing alongside a child's interests.
