The class 403 ICE 3 set, which was forming train ICE 511 (05.55 Cologne - Munich) was mid-way between Cologne and Frankfurt when the incident occurred.\r\n\r\nThe fire was detected at around 06.30 CET by a passenger who used the emergency handle to alert the driver and stop the train.\r\n\r\nThe fire started in a trailer vehicle, which was reportedly not in passenger use due to unspecified technical problems. However, passengers were travelling in both adjacent vehicles.\r\n\r\nThe train was brought to a stand in open countryside adjacent to the parallel A3 highway near the village of Dierdorf north of Montabaur. All 510 passengers and crew were evacuated, with three passengers reportedly sustaining minor injuries.\r\n\r\n\r\n\r\nPhoto: Bundespolizei Koblenz\r\n\r\nThe local fire brigade responded quickly but the train suffered severe fire damage with one vehicle largely destroyed and the adjacent vehicles badly damaged.\r\n\r\nEvacuated passengers were transferred by bus to Montabaur where a replacement train was provided.\r\n\r\nDB says the high-speed line will remain closed until Sunday evening to enable analysis and recovery of the damaged train as well as infrastructure repairs. In the meantime, trains are being diverted via the Rhine Valley route through Koblenz and Mainz, adding up to 80 minutes to journey times.\r\n\r\nEvacuation of the train was completed quickly as all ICE 3 trains using the Rhine-Main high-speed line are equipped with retractable steps due to the large number of tunnels on the line. Safety regulations requiring ease of evacuation in tunnels were introduced before the line opened in 2002.
