This video shows Delivery to installation of two Leaky Feeders for the ESN/PCN (Emergency Services Network/ Public Communications Network) trail site. The site is the tunnel section between Waterloo and Bank “The Drain” one of the most challenging tunnel sections in London Underground, driven deep under the River Thames, opened in 1898, built by John Mowlem & Co at a 2019 equivalent cost of £26 million pounds, it is 2,37km in length, to this day over 17 million passenger journey per year,

Using the Greathead Shield innovational (at the time) method  to bore the tunnel. The walls are formed from cast Iron Rings of seven segments, at some stage in the past we suspect the 1940/50’s the tunnel walls were lined with concrete, making securing fixings into the side walls an “interesting and challenging” task to be overcome.

Two Leakey Feeders and fiber optic links have been installed to achieve the toughest of test beds for the ESN/PCN. The project is currently in delivery.
