Huddersfield to Wakefield Kirkgate has no Sunday service. The Wakefield to Knottingley line didn't have for a long time, but it may have one now that the service extends to Leeds after Wakefield. Perhaps someone can confirm?
Also no Calder Valley via Dewsbury services on a Sunday, but all stations are served by other services.
The Wakefield to Knottingley Sunday service was, if I can remember, introduced last year at the infamous timetable change of May 2018. Prior to that there was nothing at all stopping at Streethouse, Featherstone or Pontefract Tanshelf on a Sunday ever since the line was reopened in 1992.
The Looe Valley Line roughly loses its Sunday service for around eight to nine weeks and tomorrow (
Sunday 31st March) it gets its Sunday service back until the end of the year. Link opens as a PDF.
The Humberlinc Line (Barton on Humber to Cleethorpes) doesn't have a Sunday service between December and May. The Doncaster to Scunthorpe branch (SYPTE Route SY1) doesn't run on a Sunday which means Thorne South, Crowle and Althorpe isn't served on a Sunday.
