For example, if you have a train schedule with stations and times, you often aren't told how the train will navigate between those stations. In some countries it's straightforward but for instance SNCF TGV services in France sometimes go hours without stopping at a station, crossing a lot of distance. In that case a solution like this can help you find an educated best guess to show users on a map.

I spent a weekend parsing PDFs into SQLite, and shipped the app with a preloaded database. Then kept updating and tweaking and added some fun intersections of the data ("who else is operating this train").

8 years later my source of data stopped providing data because of data protection concerns and the company introduced their own app/functionality for the same. Never earned me a dime directly but did get me my next job - it was a great sample for the interview
