I'm currently exploring a new business opportunity that combines my love of maps with travel. Today I know I can use Google Maps, however, I've recently heard positive things about Mapbox. Without using Google Maps, and instead using Mapbox APIs and publicly available train route data (e.g. OpenRailwaysMap or similar) I would like to overlay the exact train route on a Mapbox map between any train station. In this proof of concept I want working code that can be used to map the train route between:
London to Manchester, UK
Paris to Poitiers, France
Rome to Bologna, Italy (see attached image as an example from Google Maps)
The target platforms for this implementation should be mobile web and an Android native application.
