In the Miniatur Wunderland implementation there are sub-surface "wires" that establish pathways that the vehicles can be assigned to follow using their onboard tracking electronics. Perhaps the forklift uses a similar scheme. I do know that the vehicles, when they detect that their batteries are low, will move to a recharging station and plug themselves into it. This suggests to me that the sub-surface wires, beyond acting as a pathway, may be being used for communication between the vehicle and the computers that control the display. Such communication, if I'm right, would provide a lot of flexibility, allowing, for instance, the computers to redirect the vehicle from one pathway to another.
I didn't think of the possibility of sub-surface wires with tracking electronics. I bet you're right about that. That would explain the precision driving and repeatability. Thanks for bringing that up.
