The rapid growth of urban populations in the 19th century meant that the everyday interactions of a large amount of people required clever planning. As cities expanded, the distances between the suburbs and the city centres kept increasing. How could the city folk get to work and back, and how could they avoid traffic jams? London had an innovative idea: to take transport underground. The first underground railway was opened in 1863. Thanks to Charles Pearson, who made underground transport possible, at the invention factory you can find a special track for racing cars with steam engines, and drive them through the winding underground passageways. Take a seat in a steam vehicle that 19th-century adrenaline junkies could only dream about and whizz through an underground labyrinth!
