<p>The goal of digitalization is to standardize processes and reduce resource consumption. However, achieving this goal often requires substantial intellectual and resource-intensive investments. In this work we fokus on the automatic placement of digital signals at appropriate distances from existing switches along station tracks, replacing analog signals. In contrast to previous approaches, we extend the problem scope to better reflect real-world application scenarios by supporting multiple entry and exit tracks as well as bidirectional train movements. We formulate a constraint problem to define the problem and introduce methods to accelerate the solution process, making it scalable to large problem instances. The proposed approach is validated through a series of tests generated by our newly developed problem generator, illustrating its applicability to real-world challenges.</p>
