* Abstract

Minimizing on-site testing is a key aspect of the development of future railway control systems. For that, laboratory tools, procedures and collaboration will be improved. A coherent approach for zero on-site testing using simulation tools in a lab needs to be developed. The objective is to develop new test procedures, new open formal scenarios and new laboratory tools with the aim of reducing testing time, reducing filed testing and reproducing realistic scenarios in the laboratory. The reduction of time and effort required for testing will be achieved by automating as well as relocating tests into labs. Fully automatic conformity tests, enhanced interoperability tests and high quality operational tests are the aim. Starting from test-specification (Subset-076), including the interface description of Subset-110-111-112 and the operational scenarios from ERA, the vision is to have one powerful test bench able to proof correct behaviour in real operations as well as performance, safety, interoperability and conformity. This will reduce the effort for field testing (ideally to zero) and also decrease the effort for lab testing massively, assuring a good reproducibility. The most important thing is the proof of equivalency between field and laboratory tests. The concept presented here starts by having a look into the status quo of field testing investigating common problems and errors. This includes a description of the overall test processes, powerful test bench architecture, and an open description of interfaces. Moreover, new tools to make more realistic tests will be needed, e.g. introducing interferences in the air-gaps since EMC is still an open issue and a thread in the operation. Moreover, ETCS is a safety critical system designed against failures that do not occur during normal operation that will require a specific safety testing. This will allow creating an improved definition of new operational scenarios in a new and open format using the inputs of Subset-076 and 112. Link to requirements will be included in order to ensure full coverage between scenarios and specifications. To bridge today’s gap between the description of lab tests and field tests, special tools will be developed for easy creation of scenarios. A single European certification process will be proposed, avoiding the certification for every country. The results presented here show results from the projects ETCS Advanced Testing and Smart Train Positioning System (EATS) funded by the European Commission under the FP 7 and the project Next Generation Railway System II (NGRS II) funded by the DLR.
