The world's longest straddle-type monorail line began operation in southwest China's Chongqing Municipality on Wednesday afternoon, according to local authorities.
With its newly completed northern extension, Chongqing Rail Transit Line 3 now stretches 67 kilometers from end to end, making it the longest straddle-type monorail line in the world, according to authorities.
Many technical difficulties were overcome in the development of the monorail system, which creates less noise and was also less costly to build, authorities said. Currently, more than 90 percent of the components of the monorail trains are domestically made, they added.
"Chongqing Municipality is now at a world-leading level regarding the construction and design of straddle-type monorail systems, and the manufacturing of mechanical and electrical equipment. As for the manufacturing of prestressed concrete track beams, carriages, and trucks, and also the parallel railway switches, we are also at a world-leading level," said Wu Bo, the deputy head of the Chongqing Municipal Commission of Rural-Urban Development.
Chongqing's monorail industrial train industry is now worth billions of yuan, authorities said. The technologies are not only used by domestic cities but have also attracted attention from foreign countries, they added. Many countries, such as Brazil, India, and Indonesia, are also currently actively promoting this kind of technology.
