One of the biggest headaches? The River Thames. How do you dig a tunnel under a river when Victorian engineering was basically "pray and use more bricks"? The answer: you build a cast-iron tube and sink it into the riverbed. It was like putting a giant metal straw under the water.
Workers inside this tube had to dig through a layer of slimy, prehistoric sludge that smelled of all the dead things in London’s history. They called it "running sand" because it would literally flow like a liquid and try to drown them mid-dig. More than a few men ended up concreted into the tunnel walls as accidental memorials. It’s grim, but also strangely poetic.

The deep tunnels were so hot and humid that the clay would steam. Workers described it as "working inside a giant, damp sausage." To keep cool, they’d sometimes bring blocks of ice down with them, which would melt in minutes. At the end of a shift, a man’s boots would be filled with sweat and soil. No deodorant existed. Imagine the pong.
But did this stop the Victorians? Absolutely not. They built the world’s first electric tube railway in 1890. The trains had no windows at first because the engineers thought passengers would be freaked out by the dark. So they just sat in a metal box hurtling through a black void, listening to the screech of wheels. It was like being inside a haunted pinball machine.
