Starting in 2016, Deutsche Bahn AG will replace its Intercity and Eurocity fleets, built between 1971 and 1991, with the ICx. In the first phase, 130 ICx trains will be ordered from Siemens AG. There are later plans to replace the ICE 1 and ICE 2 models. The ICx will then cover around 70% of Deutsche Bahn’s long-distance routes, represen- ting the backbone of their business. From the start, all trains will be fitted with the latest fire protection techno- logy from WAGNER. The TITANUS® air sampling smoke detection systems will monitor the entire passenger area, actively drawing in air and capable of detecting even the tiniest amounts of smoke. The LOGIC·SENS intelligent evaluation logic guarantees an extre- mely high level of false alarm immunity. Given the space restrictions and the compact design of the vehicles, and taking design specifications into ac- count, a flexible air sampling system will be installed. © Siemens AG WAGNER Impulse | Rail News 3 FURTHER DEVELOPMENT OF FIRE ExTINGUISHING CONCEPTS WAGNER continues to develop its low pressure water mist systems New types of nozzle – New fire extinguishing concepts New system solutions, which gene- free space at the nozzle outlet to the discharge, which lasts a few minu- rate a fine water mist with excepti- allow a mist to form fully and prevent it tes, the oxygen concentration is reduced onal fire extinguishing results are hitting a nearby obstacle before it can to 10-12 % residual oxygen by volume specifically tested in technical areas actually have an effect.
