In 1888, a German city built a railway that climbs without an onboard engine: 1,849 gallons of water weigh one car down enough to pull the other 272 feet uphill

The Nerobergbahn in Wiesbaden, established in 1888, stands as Germany's oldest water-ballast rack railroad. This unique railway operates without motors, utilizing gravity and water to propel two carriages that pull each other up and down the tracks. Its eco-friendly design eliminates fuel consumption and emissions, making it a sustainable choice for transportation. With varying capacities for passengers, the railway runs from April to October, drawing approximately 300,000 visitors each year.
