I'm surprised nobody has mentioned the early morning Bristol-Stansted via New St that's run for a few years now (used to start at Gloucester)
I think that GWR don't go past Carmarthen any more, but they used to run to Pembroke on a Saturday and to Fishguard daily - done that one many times en route to/from Ireland.
Could that be the longest service run with a Turbostar?
Swindon to Southampton on GWR and Southampton to Great Malvern
This reminds me that there is also a once a day Worcester Shrub Hill - Weymouth
Not wanting to be picky here, and you probably know this in any case, but "back in the day" there were scheduled St Pancras - Leeds expresses through the day, along with portions to Bradford FS. Moreover, some went on to Scotland.
Most of these services ceased in c 1962-3, when BR decreed (understandably) that passengers for Leeds should all be routed via the significantly faster GN route with Deltic haulage (mostly).
The GNR also ran portions from Kings Cross - Bradford Exchange, but why was their route significantly faster with Deltic haulage, not exceeding 100mph? Even then, a benefit of the MML would have been the vast amount of additional capacity this provided.
Because it's simply the amalgamation of the former Crewe-Derby and Matlock-Newark services. The service along the North Staffordshire line has long originated at Crewe - hence why Longport, Kidsgrove and Alsager are managed by EMR for instance. It provides a useful, albeit rather slow, link between Liverpool/Manchester/Wales etc. and Derby/Nottingham.
Crewe - Derby and Matlock - Newark services would seem to make more sense than a Matlock - Derby shuttle. The North Staffordshire Railway chiefly provided a through Manchester - Derby route via Stoke-on-Trent, before MML provided a faster one via Bakewell, but of course Crewe - Kidsgrove was also part of the North Staffordshire Railway, as was Stoke-on-Trent - Norton Bridge/Colwich and there are no through Liverpool - Stoke services.
1631 SX Barnstaple to Axminster (with an ECS move back to Exeter).
Looks to be the only scheduled GWR operated-service that runs between Exeter St Davids and Axminster.
That does seem to be correct. It returns ECS via the curve at Yeovil, reversing at Castle Cary. I don’t know why it wouldn’t run in service beyond Axminster.
Newcastle to Banbury, one each way with Cross Country. There used to be a good service between the Northeast and the Southeast.
2 a day XC Newcastle - Banbury, these are interesting as they reverse at New Street and run via Bordesley Junction, not Soho, Moor Street or Coventry.
Through trains between St Pancras and Bradford Forster Square finished in March 1967.
There was a through train each way Leeds/St Pancras right up to the 1981 timetable, when they were 0758 up and 1650 down.
I what about Kings Cross - Bradford Exchange and the Greenside loop?
If St Pancras - Leeds continued until 1981, it never ceased as the following timetable was the introduction of HSTs until 1982. When would they have been diverted via the ECML and Wakefield Westgate, rather than the MML Wath Road Junction - Goose Hill Junction and Normanton?
Really? Continuously from the 60s? That had passed me by. I wonder why? These would have been Cl 45 hauled, no need for them to go to Leeds for maintenance. Maybe the Midland managers just wanted to keep the route knowledge for its northern depots.
There was also one advertised through working from Mansfield Woodhouse (or possibly Worksop) to Norwich, plus one unadvertised each morning until fairly recently.
I suppose these fell victims to Covid cutbacks. I don't think there were any return workings.
Obviously continuously from the 60s means continuously for over 100 years longer than that. Many services removed during Covid timetables are yet to be reinstated.
There is also an unadvertised through service from Sheffield on weekdays.
2N03 ex Sheffield joins an ECS unit from Neville Hill to form 2H03 07.48 Leeds - Carlisle.
Presumably they don't announce this as a through service because of the coupling up and faffing about at Leeds?
A through Sheffield service was advertised on the departure board at Ribblehead when I visited last year, but it would have reversed at Leeds rather than using the Leeds avoiding line which is of course part of the MML.
Severn Tunnel Jn had a few directs to/from Paddington the other week on a strike day.
That won’t be the only only unique service seen on strike days, but calling patterns were a bit broken. For example Avanti West Coast ran Lime Street - Euston via Earlestown but not calling at Warrington Bank Quay vice Runcorn and Manchester Piccadilly - Euston via Styal but not calling at Wilmslow. There is usually one train a day this way in the evening northbound only, but it calls at Wilmslow. This required passengers from Wilmslow to Crewe to double back all stops to Piccadilly.
Last Sunday, TPE (Trans Pennine Express) trains stopped at Brighouse between Manchester Victoria and York due to Engineeering work - it usually has services to Leeds and Manchester but all are slow stopping services - these were three stops to York, via Leeds and one to Manchester.
My sister took advantage of this for a day out in York. Unfortunately, on her return, the doors didn't open so she travelled to Manchester and back, too (she'd realised the platform was too short and moved to another carriage, but apparently not far enough - there were half a dozen people caught out and no announcement).
This was not only last Sunday, but both Saturday and Sunday for the last 2 weekends, TPE ran 2tph fast via the Calder Valley, calling only Brighouse and Dewsbury, despite the fact that they still ran through Mirfield, but connections to Huddersfield were available at Brighouse from the Bradford Interchange - Huddersfield service.
These were the Liverpool Lime Street - Newcastle 802 service which has been diverted that way every Saturday during Miles Platting - Stalybridge but not Guide Bridge - Stalybridge blockades, but this week and last Stalybridge itself was blocked, so it was supplemented by a pair of 185s alternating between Redcar Central and Darlington but not running around the Ordsall Chord. I made use of one for a day out in Yorkshire as I did a few weeks ago when they ran a Piccadilly - Sheffield via a Wakefield Kirkgate non-platform line.
