Hi @SamH
In many cases, you will be able to take a later train or use an alternate route to arrive at your destination if your planned route is affected. To minimise the impact on your travel plans, investigating alternatives should be your first priority when a disruption occurs.
In the unfortunate event that your journey is affected by the strikes, you may contact us after the train's originally scheduled departure time to request a full refund of the reservation fee (booking fees are unfortunately non-refundable).
Have a lovely day!
