Abstract

Yards play an important role for the quality of rail freight services. These facilities function as reassembly hubs in rail freight networks and incorporate a significant amount of static and dynamic resources. From the customer’s perspective yards are thought of as an element that adds a little value to the final product. Form the rail operator’s perspective yards are seen as a main source of delay and loss of business. Therefore, running yards inefficiently is not acceptable. In this paper, a double-ended flat-shunted yard has been studied by G/G/m queues. The results obtained demonstrate significantly low utilisation levels of the yard subsystems in question. Therefore, possible improvements through changes in traffic rules and production schemes are discussed.
