Arrive at the advanced and sophisticated Monorail Transport Base from Lego, which is a part of the Unitron series of sets. With 573 pieces this Space Lego is complicated set and stimulates the imagination. Mini-figures of three Unitron astronauts and Spyrius Cyborg are included in this Monorail Lego. This Space Lego is comprised of a Monorail track, a one-way station, two terminals, a train, and a ground vehicle. Another great feature of this Monorail Lego is that it can be placed along with other Unitron sets for hours of Lego fun. Outer-space gets even more interesting with the Monorail Transport Base.
