Grimsby to Lincoln Service frequencies in previous timetables?

[lyndhurst25]

Sorry, I wasn't very clear in that post - all the services were through from Cleethorpes apart from those two odd Barnetby starters. I only asterisked the ones with "interesting" destinations. The OP asked about the level of service from Grimsby to Lincoln, so that's what I showed.
I've edited my earlier post to clarify

Thanks. So it looks like the decision to run the trains from Grimsby instead of Cleethorpes coincided with the singling of the line and reduction in platform numbers at Cleethorpes in the 1980s.

Yes. I have timetables from summer 1996 and summer 2000. They both show the service ran Grimsby-Lincoln with most trains continuing to Nottingham and a few continuing beyond to places like Coventry (via Nuneaton). On the downside, the frequency East of Lincoln was slightly less than 2-hourly (some 2-and-a-half hour gaps during the day).

Similar frequencies in my 1989 timetable.

And IIRC with rescheduling which made turning round at Grimsby essential.

That makes sense. I left Grimsby for college in 1985 and that was the time the work started on the singling of the track and upgrade of the signalling. I still have relatives in town and make use of the TPE service.
