Abstract: The aim of digitalization is to streamline operations and conserve resources; however, the process itself often requires significant intellectual and resource investment. This paper addresses a digitalization challenge within the German railway system, focusing on the placement of digital signals at appropriate distances from existing switches along station track sections, replacing analog signals. This study serves as a feasibility analysis demonstrating how constraint programming can resolve the problem. We first formulate a constraint problem that defines the issue, then demonstrate methods to accelerate the solution process of the model, making it suitable for larger problems. This approach is validated through a series of tests using generated scenarios to illustrate its applicability to real-world challenges.
