The four-car G1 trains will replace 12 type DT2 two-car trains on Line U1 from 2021.\r\n\r\nThe trains will be built at Siemens Mobility\u2019s Simmering plant in Vienna, Austria, while various vehicle components such as drive converters, motors, auxiliary converters and control systems, will be manufactured in Nuremberg. Project management, development and service support will be handled in Erlangen.\r\n\r\nThe trains will feature wider doors, full-width open gangway, multi-function areas, passenger information systems and air-conditioning. LED lights above the door inside and on the door panel outside will indicate whether the door is opening or closing, while automatic retractable steps at all doors will increase passenger safety and improve passenger flow.\r\n\r\nThe trains will be configured for future conversion to driverless operation.\r\n\r\n\u201cWith the G1 train, we'll be launching a new era of underground operation,\u201d says VAG executive board member responsible for technology and marketing, Mr Tim Dahlmann-Resing. \u201cWe can carry more passengers, offer them greater comfort and also improve usability for people with reduced mobility. With this train running on Line U1, we can tackle the next 40 years of metro operation.\u201d\r\n\r\nFor more information on fleet orders around the world, subscribe to IRJ Pro.
