In this article however I’m only looking at LEGO-made track.

These offer myriad options for curve radius and alternate switch designs. In recent years a number of LEGO fan owned companies have started producing LEGO-compatible track, mostly in all-plastic but some have produced 9V compatible track as well.The all-plastic Double Crossover track is also not included.The all-plastic Flex Track piece is not included in this discussion that makes some track shapes easier to achieve, though trains are more likely to derail on Flex Track than normal track that is assembled according to the principles on this page.If you are using the all-plastic track you can ignore considerations of short circuits (see the Wye oh Wye? section). This page was originally written several years before LEGO switched from powered 9V track to all-plastic track with battery trains.(EDIT 1: updated URL to Internet Archive) Notes Their website is down, but you can see the Italian Translation on the Internet Archive. In 2008, I gave permission for someone from ITLUG, the Italian LEGO® Users Group, to put out a translation of this page into Italian.

While none of these ideas are original to myself (with the possible exception of the yard at the bottom), I hope this explanation will inform and inspire you to build better and hassle-free LEGO layouts. Here are some more advanced ideas for LEGO train layouts, while still keeping consistent with the restrictions of track geometry.
