From the limestone quarry at Forsby in Vingåker municipality, to the cement factory at Köping in central Sweden, once ran one of the world's longest aerial cableway. Buckets of limestone travelled for 42 kilometers (26 miles) above the green fields, through the woods and over the lake Hjälmaren.
The Forsby-Köping limestone cableway was built in 1939. Lime transport continued until 1997, but demand for lime had declined to the point that transport became cheaper by truck. When the cableway was taken out of service, it had transported 25 million tons of limestone during its 53 years of operation.
