The Wuppertal Suspension Railway is a suspension railway in a German town named, you guessed it, Wuppertal. At over a hundred years old, it is the oldest electric elevated railway with hanging cars in the world, yet still manages to transport 82,000 passengers every day. There is only one line and 20 stations that run along a route of 8.3 miles (13.3 km).
You would think that a transportation system such as this might have a lot of accidents. There’ve actually only been 7 accidents since the railways opening in 1901 and only one of those had fatalities. This happened in 1999 when workers doing scheduled maintenance forgot to remove a metal claw from the track. The next morning the first train hit the claw at about 30 mph (50 kmh), causing the train to fly off the track and into the water. Five passengers were killed and 49 injured in the accident.
Five of the seven accidents have happened in the last 50 years and four in the last 20. One accident from 1968 was caused by a truck on the ground hitting a pillar that caused a section of track to fall, but luckily no trains were on that section of track at the time.
Two accidents since 1997 have caused injuries aside from the claw incident. One was a malfunction-caused rear-end collision that injured 14, while the other was a collision with a crane truck as it tried to pass under the track. No one on the train was hurt, but the truck driver was seriously injured.
