Metro for Guangzhou Mass Transit Line3   
 

 

CSR Zhuzhou Electric Locomotive Co., LTD (the former Zhuzhou Electric Locomotive Works) , as an international famous research & manfacture base for rail transprotation equipment, has provided 70% of the electric locomotives held by china railway, and has exproted electric locomotives to Middle East and Central Asia for several times. On the basis of the strong capacity in system integration and the powerful advantage in mechanical-electric integration, with the guide and support from national industry policies, in 2001, ZELC was awarded the designated enterprise for the nationalization of urban mass transit

The consortium of ZELW and SIEMENS won the purchase order of 120 metro cars (3 cars to make up one train, 40 trains in all) for Guangzhou mass transit line three in 2003. Line three of Guangzhou rail transportation has an overall length of 36.33km, including main line and branch line, with 18 stations.
