This is the autonomous monorail people mover that evokes the steam-powered fantasy of Jules Verne or H.G. Wells. Children follow straightforward graphic instructions to snap together the 550-piece construction pieces into one of three track configurations, or clever architects can assemble the versatile pieces into as many structures as they can imagine. The monorail locomotive has a working light and both it and the passenger car bear the hallmark cogs, portholes, rivets, and visible gears made famous by early science fiction writers. The elevated track can run as long as 20 looping feet over a 25' sq. area, with the included traction tape enabling cars to climb up to 30º grades. Monorail requires 4 AA batteries. Ages 8 and up.
