I'm able to secure tickets on DB on any day of the week except Sunday. Trying to book a ticket from Trier to Luxembourg on December 11th and am unable to do so. I thought maybe it was too far in advance but I'm able to book a ticket on Saturday. There isn't anything on the DB website that indicates there isn't train service on Sundays. Can anyone confirm DB trains run 7 days a week? Thank you in advance for any guidance!
