Yes, used to go in there with my lady friend by Cooks Level. The lights would be in there and we used to quietly sneak down the incline, although no one about, lights on a timer or something.
Did explore the lower levels.
More recently, I would visit and switch the lights on in the BV incline winch house, eat my lunch, then switch them off when I left.
All history now.
