On this night in science
The first underground railway
January 10, 1863
On this day in 1863, the world's first underground railway opened in London, running through a tunnel beneath the city streets. Its trains were pulled by steam engines, and in its very first year millions of people rode it.
Why it mattered
Cities all over the world have built underground trains since then, so people can travel beneath busy streets instead of through them.
Wonder together
If you could dig a tunnel under your town, where would you want it to go?
