I did all sorts of work on that machine from electrical to building the rail the machine rides on to running the grouting machine that pumped grount to fill in the space behind the cutting head. But it’s operated on board. They are very slow moving machines the fastest I saw it moving was about 80mm per minute.
lol, no it was just called the TBM (tunnel boring machine). Most of the jokes were around the graveyard we were tunneling under. We were 65 feet down so no worries of actually boring through any graves.
