I am looking for ticket advice regarding off peak day returns (with 16-25 railcard) between Lostock (LOT) and Liverpool Lime Street via Leyland / Preston. For the purpose of the screenshots I have used Monday 25th May and requested a via Leyland route to avoid Bolton and Farnworth Tunnel. As the screenshots show, I have selected the "Off Peak Day Return valid via Wigan: 16-25 railcard". Usually on First Transpennine Expresses' this action would grey out peak services my railcard is not valid on. This is not the case however. Could someone please explain why this is the case. I know that if my ticket costs over £12 I am permitted to use a 16-25 railcard. However in this case I cannot think of any justified reason why it is allowing me to select services my tickets probably would not be valid on.
