Abstract
While track possession times (due to railway construction and maintenance works) for the most part render portions of the railway infrastructure temporarily unavailable, they are necessary to upkeep the its long-term serviceability. Therefore, possession times and the construction processes themselves must be planned and executed in such a way as to minimize the impact on railway operations. This contribution proposes an approach to determine the optimal point in time and duration of track possessions with a focus on ETCS installation. The approach utilizes mathematical modeling techniques and a hybrid between an exact and heuristic method while considering effects on the railway operations, construction management requirements, and production resource constraints like available labor force. The proposed approach enables a better capacity consumption in the railway network by allowing an optimized planning of possession times and a faster realization of railway construction works. To validate the approach, the results are compared with real-world track possession time planning.
