The contract covers the conversion of the existing train control system to ETCS Level 1
Limited Supervision and the maintenance of the existing signaling system for 25 years. The system will be delivered in eight geographically defined implementation phases in the period between 2012 and 2017.

"Together with SBB, we have developed, tested and optimized two prototype stations with the
systems that are going to be used. The longstanding working relationship between SBB and
Siemens will help us convert the route network, which currently has some 10,000 automatic train control elements, within the tight time schedule," said Jochen Eickholt, CEO of Siemens Rail Automation Business Unit.

"In upgrading the existing train protection system to ETCS Level 1 Limited Supervision, we are taking the first major step in the Swiss ETCS strategy which is aimed at the sustainable optimization of the railway network," emphasized Philippe Gauderon, Head of SBB Infrastructure and member of the SBB Management Board.
