Exchange MYHUD has gone live, the revised date for cab 154 going live was sometime late 2013, then 31/03/14 and then 31/05/14. Given the latest date has been missed, and although there was updates to Roadworks.org twice in April, no work was carried out at the cabinet.
There's two pictures. One shows the power cable to the cabinet (they did this ages ago) but I can't hear a hum at the cabinet. That is probably due to it being on a busy road. The second shows some yellow coding sprayed near the duct. My guess the "4ft" refer to exending the duct, and the "2" between the parallel lines is some sort of indicator to connect the PCP to the Fibre cabinet? There is a yellow trail to PCP cabinet but its not clear in the photo
The Tour de France will pass down this road before the cabinet goes live I reckon
