How this service works
Rail re-planning for a traveller already on a delayed train: the best onward options, concrete transfer alternatives with buffer transparency, and a specific recommendation — fast and cheap, instead of the agent researching several routing APIs itself.
Output
A structured response containing evaluated onward transfer options from the traveller's current position, each with connection timing, buffer transparency, and feasibility indicators, plus a single concrete recommended route that balances speed and cost.
Example use cases
Delayed ICE rerouting mid-journey
“I'm on trip ICE-792 heading toward Munich, but we're running 30 minutes late. I need to reach Augsburg (stop ID 8000013) — can you check what transfer options I still have with at least a 10-minute buffer and tell me which one you'd recommend?”
Missing a tight connection at a hub
“My train trip ID is RE-4451 just got delayed by 15 minutes and I'm worried about my connection at Frankfurt. My destination stop ID is 8000105 — what are my realistic transfer alternatives and which is the best one to take?”
Proactive rebooking for business travel
“I'm on trip ID IC-2371 and there's a manual delay of 40 minutes shown on the board. I need to reach Berlin Hbf (stop ID 8011160) with at least a 12-minute buffer for each transfer — what's the smartest chain of connections I should switch to?”
Technical details
Endpoint
POSThttps://bahn.1f916.de/api/transfer-chain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when a traveller is already mid-journey on a delayed train and needs immediate, actionable rerouting advice rather than a fresh journey search from scratch. It is purpose-built for the delay-rebooking scenario on the German rail network, combining delay awareness, buffer calculation, and a single recommendation — saving an agent from orchestrating multiple routing API calls and synthesising results manually.
Side effects
- Invalid or expired trip_id returns an error with no alternatives
- Unknown destination stop_id results in no routes found
- Extreme delays may yield zero feasible transfer options
- Manual delay string in wrong format may not be parsed correctly
- Stale cache from cache_ttl may return outdated connection data
