MUNICH (dpa-AFX) - Siemens is to equip the entire suburban railroad network in Copenhagen for autonomous trains. The company announced a major order on Monday for the upgrading of 170 kilometers of track and the supply of the associated technology for 226 new trains. The trains themselves are not part of the current order. Fully automated operation should be possible by 2033, said Siemens Mobility CEO Michael Peter. "This will make the Copenhagen network the world's largest automated urban rail network." The current agreement, worth 270 million euros, builds on a contract from 2011, under which Siemens upgraded the network to a lower level./ruc/DP/ngu
