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)

==> national technical prescriptions remain vitally imp ortant !!!!

Notification -Database

Main problem:localization / reference points

More than 1000 notifications

More than 4000 documents

> 80.000 pages

> 1000 maps

Track database

Task:

1. complete digitalisation of

urban rail network [CUBAL]

2. automated actualization of

reference data [NetScan]

3. all-embracing coverage of

infrastructure data

Track database

detail vs. overview

1. Technical control has to be

possible as well as

2. Economical design, planning

and control
