| contents | The freight branch of the Swiss national railways, SBB Cargo, offers customers to ship single or few wagons within its wagon load transportation system (WLV). In this system, wagons travel along a transport chain which is a sequence of consecutive trains. Recently, SBB Cargo redesigned its IT systems and renewed the computation of these transport chains. This paper describes the main design decisions and technical details: data structures, search algorithms, mathematical optimization of throughput in the real-time setting, and some selected details for making the algorithms work in the operational software. We also comment on the employed technology stack and finally demonstrate some performance metrics from running operations. |
