Arriva Trains Wales: Fares to rise in 10p increments
Fares on Arriva Trains Wales services are to go up by at least 10p from 2 January 2015.
It said the rises follow an increase by the Welsh government which is set at 2.5% or 10p - whichever is greater.
Last month Transport Minister Edwina Hart said that increase would be the maximum allowed on regulated fares.
An Arriva Trains Wales spokesman said a 10p increment "can sometimes mean that the very lowest fares increase by more than 2.5%, which is permitted".
