Title:
Abstract:	In very long rail tunnels (> 20 km), emergency stations (NHS) are provided for trains to stop in case of an incident. Emergency stations are constructionally detailed and equipped so that the passengers can be evacuated quickly and safely in case of an incident such as a fire in a train. Such emergency stations are provided in the existing Lötschberg Base Tunnel (CH, opened 2007) and similar tunnels that are currently under construction, the Gotthard Base Tunnel (CH), Brenner Base Tunnel (A), new Semmering Base Tunnel (A) and Koralm Tunnel (A). The present article compares and explains in detail the ventilation and safety aspects of emergency stations and the construction detailing, ventilation and safety equipment, which have to be considered in the design of an emergency station. In sehr langen Eisenbahntunneln (> 20 km) werden sogenannte Nothaltestellen (NHS) für den störungsbedingten Halt eines Zugs vorgesehen. Die NHS sind baulich und technisch so ausgestattet, dass im Störungsfall, z.B. bei Zugbrand, eine rasche und sichere Evakuation von Fahrgästen ermöglicht wird. Im bestehenden Lötschberg Basistunnel (CH, Inbetriebnahme 2007) sowie den sich im Bau befindlichen Gotthard Basistunnel (CH), Brenner Basistunnel (A), Semmering Basistunnel neu (A) und Koralmtunnel (A) sind solche NHS vorgesehen. Im vorliegenden Beitrag erfolgt eine Gegenüberstellung der baulichen und lüftungs- bzw. sicherheitstechnischen Ausgestaltung der NHS. Die projektspezifischen Randbedingungen und Vorgaben, die bei der Planung der NHS berücksichtigt werden mussten, werden im Detail erläutert.
