Title says it all really, but I've tried through three separate booking engines (ATW, GWR and Cross Country) to reserve seats on various services (23 Dec 1037 and 1137 Derby to Newport, and 27 Dec 1200 and 1301 Newport to Derby) but in each case it's saying reservations are not available. In each case the ticket is an off-peak return with senior railcard. Could anyone explain this to me please, and ideally help me sort out how to get reservations? They're for an increasingly elderly parent who would be uncomfortable with the thought of travelling without a reservation.
Thanks very much in anticipation.
