About isar GmbH

isar GmbH, based in Cremlingen near Braunschweig, is an engineering service provider for safety-related testing and system assessment in the field of railway and signalling technology. The company tests protection logics, control and monitoring logics as well as software changes to Electronic Interlockings of the SIMIS and SICAS types, including the ECC and INOM subsystems. The service portfolio also includes theoretical plan reviews for conversions and line extensions as well as assessments in accordance with the CENELEC standards EN 50126, EN 50128 and EN 50129. Projects cover mainline, light rail, metro and industrial railway applications in Germany and abroad, among others for DB AG, Siemens AG, international metro operators and industrial operators such as RWE Power and Vattenfall. Since 1988, projects have been documented, among others, in Hungary, China, Hong Kong and Austria.
