Disruptions data queries

[ciaran haines]

I'm setting up to do some network predictions in the future and am starting to ingest the necessary data. What I'm looking at currently is any predictive power in the free text stuff. My general idea is something using historic delay attribution data and the text from the generating incidents to do something like a delay probability prediction. 

I'm not a noob but I have been ignoring this data for a while. Apologies, but I'm hoping to crowdsources away my inevitable stupid first pass mistakes. 

• The NationalRail Disruptions API seems to be incidents organised per station, and it seems like the wrong way to get the global incidents data. Are the incidents in the NationalRail Disruptions API the same as the incidents in this feed Knowledgebase Incidents data?
• I assume many incidents are closed, but not all?
• Are the incident IDs referenced anywhere else - Darwin timetable updates?
• Is there anything else obvious I'm missing, apart from `free text fields = awful`?

Thank you all in advance for any help!
