Optional extras for this LEGO set. Not official LEGO products unless stated otherwise.
Simple Duplo expansion: a tunnel segment that can be mounted over the Duplo rails, plus extra straight rails to extend the layout. Designed to combine with the 10427 or 10428 Duplo trains.
20 pieces, ages 2+. The tunnel is tall enough that a Duplo train can pass underneath, and the facade has colourful decals (mountain stones, bushes) for role-play context.
RRP €19.99. A typical "stocking stuffer" Duplo: small, cheap, expands the existing layout. For families adding to their Duplo train collection.
