Legal conditions:Austrian Railways Act (EisbG)
§ 19a continuous monitoring
§ 40 railway engineering special fieldsRequired for continuous monitoring of railway infrastructure⇒⇒⇒⇒
� Railway undertakings without a certified safety management system due to§ 39c, have to undergo a routine periodic examination , stating that railway infrastructureis fulfilling the prescriptive values of the Austrian railway act (EisbG) (due to 31.12.2008for enterprises existing prior to April 1st, 2002)
� Examination is done by notified bodies, civil engineers,engineering offices and selected persons due to § 40 EisbG (with certain limitations)

Task:
1. complete digitalisation of
urban rail network [CUBAL]
2. automated actualization of
reference data [NetScan]
3. all-embracing coverage of
infrastructure data
