Good day to all,
I went to the national rail uk website and entered my date and such. Then it sent me to the Thameslink website. It is from Kings Cross to Cambridge. Then when I decided on a time and such and printed it, it was on the Great Northern Train line. So I went directly to Great Northern train website and the icon shows there also. I checked Mon and Tuesday, 6 and 7 October, and that icon is on multiple trains.
Check out 8:18, 8:48, 9:12, 9:42, 10:12, 10:21, 11:12, etc. on 6 October. At that point I stopped looking and recording.
I am guessing, but on trying to find an answer, it seems to me that it MAY have something to do with trains that are scheduled at certain minutes past each hour and maybe this is a deviation of that. The particular time I wanted was almost sold out so I went with the purchase. I hope I haven't messed up. As I said earlier, of the 3 tickets I purchased, this is the only one that is not reimbursable.
In planning an itinerary, it all hinges on getting to the location at a particular time so the rest of the day can be planned. So I hope I do not encounter any obstacles. I have scheduled plans that begin an hour after arrival so I need this to work. It is not just a day of wandering Cambridge so I am hoping for the best.
Again, many thanks to all of you for your advice and wisdom in helping me to navigate train service in England! The best to each of you!
