Thanks for the quick reply - understood, that's clear
The API is really unhelpful though, it means you have to know possible destinations in advance for every station, or pull a current timetable (multiple times since LDBWS only allows 10 rows per call) to research destinations for a station. That would significantly ramp up the number of data calls which is somewhere I don't want to go.
Do you know if there is there a resource that gives possible destinations for all stations please?
If not, I'm working on a server back end and have access to PushPort so thinking I could parse this from eg: Snapshot data and store a static matrix as a best approximation, would only have to store the from/to CRS so needn't bee too bulky. Does that sound a sensible compromise?
