Guides

What the planner knows about the track, written down: measurements, set contents, layouts worth building and what fits what. Every layout drawn here opens in the planner.

• How to plan a LEGO DUPLO train track from the pieces in the box

  What the DUPLO curve and straight measure, what each train set contains, and the layouts a box can actually make.

• BRIO track geometry: why some loops close and others nearly do

  The lengths and angles of BRIO wooden railway track, the Vario System that absorbs the difference, and what the switches and bridges measure.

• Ten train track layouts worth building, with the pieces you need

  Layouts from the boxes, the BRIO guide and the woodentracks sheets, drawn out with the exact pieces each takes, and a link to open each one.

• Which LEGO DUPLO train sets come with track, and how much

  Every current DUPLO train set and expansion with its exact track count, the 2025 changes, and why pre-2018 track is different.

• BRIO track packs: what each one adds to a layout

  The BRIO expansion packs with their exact contents, and what each piece lets you build that you could not before.

• Which wooden train track brands fit BRIO, and which only seem to

  Thomas, Melissa & Doug, Bigjigs, IKEA LILLABO, Hape and supermarket track against BRIO: what plugs in, what closes a loop, what does not.

• Points, sidings and passing loops: getting two trains running

  How points work in DUPLO and BRIO, why every siding needs a stop, and the passing loop and balloon loop that let two trains share one layout.
