Prometni institut Ljubljana together with Slovenske železnice and SŽ-Potniški promet participates in the international project In2Stempo. As part of this project, we have developed an information solution that enables passengers to have information about the occupancy of the train available even before boarding the train and to validate the ticket at the self-service validation terminals at all entrance doors on the train. The developed solution is being pilot tested on the Siemens Desiro 312 passenger set, which runs on various routes in the territory of Slovenia.
