O ti i d i i t lOptimized engineering tools
The newly defined and optimised The newly defined and optimised tool chain used by both SBB and Siemens is based on a shared databasedatabase
This made it possible to at least partially automate many steps of the
i iengineering process
Verification and validation steps have also been automated as far as possible
As a result the amount of work required for engineering could berequired for engineering could be reduced significantly and the number of errors minimised

D t f li i i t i d Data from earlier engineering steps is used as starting point
The tool guides the engineer through the data g g gcollection process by providing detailed information on the data to be collected for each signal, based on data from previous engineering stepsg g
As far as possible data values are proposed to be acknowledged, but manual entry is possible too, including adding pictures and sketchesincluding adding pictures and sketches

Conclusions
As has been shown it is possible to convert an entire railway network of 3000 km with 11’000 signals in five years to ETCS by using the Limited Supervision ModeMode
The result will be full network access for operators with rolling stock only equipped with ETCS Level 2 onboard systems (no legacy systems or STMs required), significantly reducing cost and complexity
The cost of maintaining the network will be reduced The cost of maintaining the network will be reduced too, as all components of the legacy systems are removed, eliminating the need to hold spares, train personnel etcpersonnel etc.

Conclusions
Extensive pre-studies and prototyping has helped to develop the concept and to reduce the risk for both SBB and it’s suppliers
The envisage cost reduction by a factor 4 has been achieved largely thanks to optimized processes in engineering and installation, procurement of larger volumes and development of innovative and optimised products
Even the future conversion to ETCS Level 2 will be Even the future conversion to ETCS Level 2 will be simplified, as rolling stock will be equipped faster with ETCS
Limited Supervision is only a first step in the rollout of ETCS in Switzerland, but one that significantly

accelerates the conversion of the entire network
