This time we go many meters underground to explore a giant abandoned machine, which was used to make subway tunnels and which does not have long to live.
This is one of the two tunnel boring machines that were commissioned to build line 9 of the Barcelona metro. Works have now resumed, as well as the commissioning of the Llobri tunnel boring machine.
While Besi will disappear one of these days.
Thanks to all the people who have participated in this unforgettable adventure.
