Hi Tom,

I finally got round to checking out the location of the tunnel in ACO. I’ve nailed it down to the southern side of Wandsworth roundabout. No question about it because

1. In the film you can just make out an access door about 30 yards after the tunnel to the left. See pics compared to movie frame.

This goes into some underground storage area probably for gardening equipment.

2. You can make out the original fixing point for the ‘light boxes’ on the walls by the slightly flattened concrete, devoid of any texturing. Just barely visible in some of the pics. Yes, there are these flat spots all along the tunnel(s)!
