Abstract

With safer, cheaper and sustainable transportation of goods attracting major interest in recent years, rail freight is becoming increasingly attractive compared to road freight transport. For railway timetabling, this requires a better utilization of the infrastructure's capacity. However, the unpredictable nature of this growing rail freight demand poses numerous challenges to infrastructure managers, one of them being the short-term scheduling of additional freight trains within existing timetables. Indeed, residual capacity management is a good lever to accommodate freight transport requests, while ensuring safety and minimal disruption of passenger trains. Despite its significant relevance, this problem has received relatively limited attention in the literature. This presentation aims to describe and formalize the problem, to position it within the literature and to introduce a first solution approach. Computational experiments and their numerical results will be discussed.
