I've submitted a delay repay claim. A to B with TOC A B to C with TOC B Two tickets held, split point was at B. Delay occurred with TOC B. I've claimed delay repay giving details of intended vs actual trains travelled on and listed (with attachments) tickets used. However, I've just realised I used the first ticket on TOC A at a time it wasn't valid due to the time of day. This was not detected on the day. Could TOC B who I've claimed from reject (or reduce the amount of) my delay repay claim on the basis I used the first ticket at a time it wasn't valid? I am hoping they might not notice the oversight either.
