The Monorail straight track is built with QUARKS.

The turns (Left, Right, Up, or Down) are built with a combination of QUARK's and 15 Degree Strange QUARK's

It's easy to build a few inches off the ground, but as soon as you start climbing to higher elevations, you will need to gain an understanding of cross bracing, sheer strength, and an array of other building techniques that are used in the real world. 

The model seen here, is still available at a few retail and e-tail locations, but supplies are limited.

FYI: We are planning to launch a new model of the X57 MONORAIL in Fall of 2011.
