If a train is cancelled due to a strike, the ticket can usually be refunded or rebooked for a train running on the same day free of charge (up to a maximum of one month after the date of travel). Please contact the office that issued your ticket to request a refund.
In the event of a suspension of service on the line, please enquire as to whether your train is being rerouted, whether your ticket is valid on another connection and whether it is possible to get a free refund. Any potential free refund is only available from the office that issued your ticket.
