Lausanne Triage, owned and operated by SBB Infrastruktur, is one of the most important terminals in Switzerland - 20% of inland wagon-load transport volume is sorted and classified here. The marshalling (classification) yard is located in the Lémanique region. After May 2006, the importance of this yard increased due to the concentration of train-formation processes in Swiss inland transport.

Problems and study goals

Prior to the concentration of train-formation processes in Swiss inland wagon-load transport, few important questions needed to be answered:

  • Can Lausanne Triage marshalling yard handle the increased volume of incoming wagons?
  • Is it necessary to expand reception group and classification group to accommodate the increased traffic volume?

Another key question concerned the feasibility of relocating locomotive maintenance facilities from Lausanne passenger station to Lausanne Triage marshalling yard.

Study results

Several simulation experiments were conducted to answer these questions. The results showed that the marshalling yard would be capable of handling the increased wagon traffic under the proposed operational concept. The study demonstrated that there was no need to expand the reception or classification groups. This information helped save substantial infrastructure investment costs. A further important outcome of the study was the conclusion that relocating the locomotive maintenance facilities to the marshalling yard would not adversely affect operations and was therefore considered feasible.
