Track System Overview

The diagram below shows an overview of the LEGO® train track system. A nominal 16 stud grid interval is superimposed on the diagram to show that many track relationships are nominally aligned to 16 stud intervals. A convention of maintaining 16-stud spacing between adjacent parallel track centres is very widely adopted and is strongly recommended. The 16 stud interval is also very common among many LEGO® baseplate sizes and therefore track elements can often be mounted to baseplates with connector ends flush to the baseplate edges.

LEGO® brand and ME Models track elements are shown together in this diagram. In order to differentiate the two product sources, LEGO® brand track is illustrated in red.
