DUPLO trains have been part of the range since 1983, when push-along trains and DUPLO track first appeared. Electric trains followed in 1993, with a motor in the locomotive, and since then the line has come back every few years with a new design, a starter set and add-ons such as a station, a bridge, a tunnel and a level crossing. 10874 Steam Train from 2018 brought in coloured action bricks laid on the track, which make the engine stop, sound its horn, turn on its lights or change direction as it passes over them. The trains have also been a way to learn numbers, as in 10558 Number Train, and the 2025 trains are interactive too.
1988 LEGO Sets
In 1988, Castle introduced the Black Knights era with imposing fortresses and dragon heraldry, while Town delivered large, feature-packed sets such as racetracks and service complexes. Futuron and Blacktron—introduced the prior year—remained central to Space, with sleek exploration craft set against bold, antagonist designs.
