Vision Zero (zero fatalities)
System designers are responsible for
the design, operation and the use of
the transport system
Users are responsible for
following the rules for using
the transport system
If the users fail to comply with
these rules the system designers
are required to improve the system

Compared to modern solutions available
on the market our old LX control system
design from 1970 is characterized by
•

at least 50% higher investment cost
at least 60% higher maintenance cost
at least 400% higher energy cost

Project ALEX
• ALEX – Automatic Level Crossing system)
– Procurement of modern techniques for level crossings
– Framework agreements with 2-3 suppliers according to the Public
Procurement Act
• Outsourcing policy
– Purchase of maintenance, systems etc. from suppliers
– Suppliers must take responsibility for the supply of components and
safety cases during the economic lifetime, for about 25 years
– Suppliers can introduce new technologies in their systems when it is
beneficial to both parties – Win-win!
– Safety case according to EN 50126 (RAMS)
