Rail transport is so variable that the range of suitable check-in devices is very diverse. A regional line leading through a low population density area features requirements different from city and suburban railways replacing a metro.
The check-in method in a city railway is largely similar to the metro one.
Suburban and intercity railway
Suburban and intercity railways generally place less emphasis on access control and, conversely, may feature greater requirements for fare complexity. It works with more complex tariff systems for intercity transport. Self-service terminals and stationary validators or ticket markers are mainly used for check-in. The important element also rests in the equipment for conductors, who often act as an additional way of ticket selling.
In the case of regional railways, self-service fare payment directly in the vehicle is used more often. For example, using AVJF or MVB mobile automatic devices or validators.
