There isn't!I'm with @John C . Terminated at Skipton and another unit operated from Sheffield to Nottingham? Can't see any likely diversionary route if the line beyond Skipton towards Leeds is closed.
RTT has it sat in the platform and then leaving - obviously no-one cancelled the train on the system and made it a class 5Bit odd. Delay of 3 mins due to the blanket speed restriction, 16 mins due to a track defect, 31 mins due to flooding and then held at Skipton for 19 mins (according to the system). As far as I can tell the 158 terminated at Skipton and went into Broughton Road sidings, but there's no allocation on the system for what worked onwards from Sheffield.

There isn't!
If it was reformed as sounds the most plausible reason, I wonder why the headcode remained the same?
You won't have the problem of two trains with the same headcode being at (or near) the same location at the same time - the problem isn't just with "the systems" but also the risk of signallers and other staff getting confused, potentially including during safety-critical comms.If the original headcode train had terminated at Skipton there's no real issue restarting another train with same headcode at Sheffield. After all even on Northern there are trains running with the same headcode at the same time in different areas. The systems don't much like two trains running to the same station with the same headcode hence the 1Z**
Also saves having to get NR to put a new train in the system at short notice.
Probably a convenient linking of two separate services which allows day trips from Nottingham/Sheffield along the Settle to Carlisle line.What is the reason this service between Carlisle, Sheffield / Nottingham exists? Why does this through service operate only once in each direction every Sunday?
It's a matter of rolling stock diagramming convenience, I would have said. Services on the S&C run to a relatively irregular timetable (more resource-led than clockface) and accordingly this may simply be what works out as being convenient. Somewhat similarly to how there used to be the "tour de Yorkshire".What is the reason this service between Carlisle, Sheffield / Nottingham exists?

It runs in the standard Nottingham-Leeds path, so I am sure you are right as far as recent years are concerned.It's a matter of rolling stock diagramming convenience, I would have said.

There is a day tripper market northbound with around 50% come back on the southbound, but southbound there is a lot of students from the S&C/aire Valley that go down to Sheffield and NottinghamIt runs in the standard Nottingham-Leeds path, so I am sure you are right as far as recent years are concerned.
I have a feeling, though, that the northbound train (if not both) predates that and started from Sheffield. I wonder if there is a bit of a Sunday market for Sheffield or Nottingham to Glasgow (probably students), but I've never used the train to find out, so that's purely a guess.
(Maybe I'm remembering that Leeds-Lancaster was Sunday evenings only for many years for a similar market.)
More to do with operational convenience but you’d like to think somebody from marketing & train planning also shew a little enthusiasm.What is the reason this service between Carlisle, Sheffield / Nottingham exists? Why does this through service operate only once in each direction every Sunday?
Thanks, makes sense - prime home territory for people studying away-but-not-too-far-away from home (plus those at Lancaster, York, etc )There is a day tripper market northbound with around 50% come back on the southbound, but southbound there is a lot of students from the S&C/aire Valley that go down to Sheffield and Nottingham
I fully understand why. Nottingham to Glasgow is not an easy journey these days, especially for elderly people with luggage who don’t like changing trains. I don’t mind changing trains, but the last time I travelled up to Glasgow from Nottingham midweek, I changed at Leeds and Carlisle.I know 2 unrelated people (who have no real interest in the railway) who have mentioned the convenience of getting up to Glasgow from Nottingham (and the other from Chesterfield) with just 1 change on a Sunday.
It isn’t necessarily something I’d find too appealing and I’m not that far from that starting area but I suppose I can understand.
