BT OP is normally sold as a VNA truck.
If it was rail guided then there will be roller wheels bolted to the lower corners of the chassis to guide it along the rails in a narrow asile.
If it was wire guided then when you lift the cab there will be a big bar bolted between the front chassis legs with a wire guidance aerial in the middle of it.
Which ever of the 2 possible systems could be fitted means the truck can guide itself down a narrow asile without the operator touching the steering wheel.
Dont see many OP sold as free ranging trucks but yours could be.
Does it lift the cab / forks ok?
