Train layout planner for LEGO® track, in the browser

Lay out your LEGO® City track on screen, add turnouts and curves from TrixBrix and print the parts list before you build.

A LEGO® train track planner

Put straights, curves and turnouts together, and the pieces snap into place on their own. In 3D you see the layout on the carpet before you buy a single piece.

LEGO® City and LEGO® 9V track

The starter ideas in the app are built with LEGO® City track, and two of them are shown below. The older LEGO® 9V track is in the catalogue too, but it is no longer made.

More turnouts and curves with TrixBrix

TrixBrix from Poland makes track for LEGO® trains, with more curves and turnouts. It can be combined with LEGO® City track, and the planner lets you use both in one layout.
