VR Group is currently the only company providing passenger train services in Finland, with less than optimal success in timeliness. Some time ago VR released a service for tracking train status and location in real-time. The service also informs how much each train is delayed.
The founder of Junainfo, Mikko Jokinen, provided me with a chunk of archived data from Jan-Feb 2015. The data has wealth of potential for analysis, but for a quick look here is an animation that illustrates the pulse of trains that VR has tracked for some weeks in January 2015.
