Only children under 4 are free, as they are considered lap children and do not need a seat.
You would only buy them a ticket if you wish for them to have their own seat.
Any children 4 years old and over require tickets, and the tickets are not free.
The child age ranges are under 12 for Regional trains, and under 15 for high speed trains.
