We went up in the lift to the Buck Street entrance. At the top of the lift is another Ministry of Works sign and room containing an original Hackbridge transformer for powering the lift and another metal cabinet that would have housed the mercury arc rectifier. The cabinet door was jammed but none of the equipment appeared to be working. Round the other side of the lift shaft was the motor room. The motor appeared to be a more recent addition.
Steps lead up to a winding passage leading to the emergency exit.
This passage is rubbish strewn and appears to be little used. Returning to the main tunnel, we are now in the final quarter of the shelter. At the far end, there is a door in the end wall with a final cross passage to the parrallel tunnel and a steps down to the lower landing at each end. As at Belsize Park , we were given a free hand to go anywhere and photograph anything and spent around three hours in the shelter.
