  The digitalization of railway systems should increase the efficiency of the
train operation to achieve future mobility challenges and climate goals. But
this digitalization also comes with several new challenges in providing a
secure and reliable train operation. The work resulting in this paper tackles
two major challenges. First, there is no single university curriculum combining
computer science, railway operation, and certification processes. Second, many
railway processes are still manual and without the usage of digital tools and
result in static implementations and configurations of the railway
infrastructure devices. This case study occurred as part of the Digital Rail
Summer School 2021, a university course combining the three mentioned aspects
as cooperation of several German universities with partners from the railway
industry. It passes through all steps from a digital Control-Command and
Signalling (CCS) planning in ProSig 7.3, the transfer, and validation of the
planning in the PlanPro data format and toolbox, to the generation of code of
an interlocking for the digital CCS planning to contribute to the vision of
test automation. This paper contributes the experiences of the case study and a
proof-of-concept of the whole lifecycle for the Digital Testfield of Deutsche
Bahn in Scheibenberg. This proof-of-concept will be continued in ongoing and
following projects to fulfill the vision of test automation and automated
launching of new devices.
