The Monorail System lets you add rail transportation, depots, stations, and sidings anywhere in your Rokenbok world.  Monorail tracks are made from standard Rokenbok construction pieces, so it's easy to add rail switches and crossings, or build tall trestles and drive your Monorail through multilevel Rokenbok worlds.  The ROK Star Controller sends the Monorail engine gliding down the track, and commands the Monorail's powered cargo bed to load or dump.  In fact, the Monorail interacts with every vehicle and machine in the Rokenbok fleet!
