About Trains

Why trains suit Duplo

Few toys are as easy for a toddler to understand as a train: lay the track, put the engine on it, push. Duplo keeps that simplicity with chunky rails, sturdy engines and wagons built from ordinary Duplo bricks, so every train can be rebuilt into something else. Over the years the range has included push-along trains as well as electric ones such as the Deluxe Electric Train Set (2745-1) of 1996, which has 88 pieces.

The Deluxe family

One name keeps coming back among the largest sets. The Deluxe Train Set appears as 3772-1 in 2005 with 113 pieces, as 5609-1 in 2008 with 116 pieces, as 5609-2 dated 2012 with the same 116 pieces, and as 10508-1 in 2013. That last one, at 134 pieces, is the biggest set in the whole theme. When buying second-hand, the set number matters more than the name, because the name alone does not tell you which edition is in the box.

Freight, Explore and the newest trains

The Cargo Train (10875-1) from 2018 has 105 pieces and focuses on goods rather than passengers. The Intelligent Train Deluxe Set (3325-1) of 2002, with 94 pieces, dates from the brief period when Duplo was sold under the Explore name. The most recent large set is the Big Interactive Community Train (10428-1) from 2025 with 103 pieces.

Sorting a second-hand railway

Inherited train sets often arrive as a jumble of track, engines and loose bricks. The parts lists on Bricoria let you untangle that set by set, and licensed trains such as Thomas & Friends have a theme page of their own.
