Planned ascent missed; passengers move to the 18:30 cabin. Capacity on that cabin must absorb 48 additional passengers.
Hotel / activity
Arrival 18:48 — destination commitment unaffected.
Passenger communication
- · Passengers on IC 718 and RA 34 with onward journeys
- · Bus 12 passengers at Aldern Bahnhof
- · Cableway ticket holders
4 · Decision support
Options for the people responsible
Each option names who would decide. None is executed by the system.
- Decision support
Consider holding Bus 12 by up to 10 min
Protect the rail–bus interchange at Aldern Bahnhof.
Why?
- 64 passengers transfer from RA 34 to Bus 12 (synthetic count from ticket mix).
- Next Bus 12 is 20 minutes later.
- Bus 12 has 6 minutes recovery time at Talstation, so a short hold is unlikely to propagate.
Decided by: Local bus operations controller
- Decision support
Publish a coordinated passenger message
One consistent message across train, station, app and partner channels.
Why?
- Passengers otherwise read different information on different screens.
- Additional journey time: 15 min.
- Draft only — wording and channel remain with the passenger information team.
Decided by: Passenger information team
Draft passenger message
Your journey to Hochfirn is delayed. Expected arrival at Berghaus Hochfirn is now 18:48 (15 min later than planned). Onward connections at Aldern have been re-planned. No action needed — follow station announcements.
Draft for review by the passenger information team. Not sent.
Decision support. Recommendations are presented for human judgement. This is not autonomous dispatch — operators and commercial teams remain responsible for every decision.
Synthetic demonstration. All operators, places, services, staff and figures shown here are fictional and generated for demonstration purposes. No real operational or passenger data is used, and no client relationship is implied.
