Innovative service and operating concept for S-Bahn transport
Customer: Forchbahn AG, Switzerland
Project tasks
- Scenario and variant supply and operating concept 2035+
- Concept for on-demand operation with ATO
- TARGET system architecture and gap analysis to the ACTUAL system landscape
- Determination of requirements for later migration of the new vehicle
Our approach
PROSE supported Forchbahn in the tendering process for a new vehicle fleet. This also raised questions about the future service and operating concept of the S18 Zurich Stadelhofen – Esslingen line. In order to utilise the opportunity of a new vehicle fleet, PROSE developed various scenarios regarding vehicle lengths and the change in the current service concept through the use of automatically operated vehicles in the direction of on-demand operation at off-peak times. The scenarios were developed for different service levels, depending on the time horizon.
Based on the existing old vehicles, the timetables, the planned timetable and the frequency surveys of current operations, we analysed possible vehicle concepts and the resulting number of new vehicles. We specifically analysed the possibilities with long and short trains as well as the operational and technical reserves. We also developed a 2035+ service and operating concept using fully automated multiple units on the Forchbahn’s infrastructure. In addition to the migration and service steps in the introductory phase, this also included the concept for the introduction of on-demand operation during off-peak times. The tender process defined a target system architecture and vehicle requirements for future migration.
Customer benefit
Based on the actual data, PROSE conceptualised the target state and derived opportunities and risks for the respective thrusts in the service and operation. These were reflected in workshops with those responsible at Forchbahn. The results were integrated directly into the tender documents. This ensures that the vehicles are suitable for operation in the long term and that nothing stands in the way of the subsequent implementation of ATO-on-demand operation. PROSE’s knowledge helped Forchbahn make well-informed decisions early in the process, reducing future risks and supporting long-term operational efficiency.
