Has 1B00 gone then? The one that was non-stop Chesterfield-London?
Yes 1B00 - The Master Cutler is no more. Now replaced by 1C20 but starts at Sheffield and calls at Chesterfield, Derby and Leicester. On another forum heard that this service was full and standing by Derby, even in first class.
The problem is that it is a Meridian and that two HSTs leave Sheffield 5 and 17 minutes after with nothing for 30 minutes before. I think some changes might be needed.
Also the following are missing from that list:
1F00 0620 - DBY-SHF (goes via Beigton)
1F01 0720 - DBY-SHF
1C86 2039 - SHF-STP
1C90 2321 - SHF-DBY (goes via Beigton)
