The only 31 I ever had on the WCML, unaccountably I did not record the details, was when a Down freight damaged the overheads somewhere between Carlisle and Lockerbie. The only loco available at Carlisle for an Edinburgh-bound train was a 31, which worked the train (slowly!) via a reversal at Carstairs, from where I took a bus to Lanark for a train home towards Glasgow. I'm not even sure what year this was, possibly 1986-87.
The only info I can find on class 31s working passenger trains at Carstairs in the late 80s is this snippet from the September 1985 Rail Enthusiast:
31165 (BS) made a virtually unprecedented visit to Carstairs on June 3 [1985] when it was forced to carry on with the return working of a Scotrail Explorer excursion from Arbroath to Morecambe instead of being taken off at Carnforth when 85023 was declared unfit. It was then relieved by 47528.
And this working from the
Railgen archive:
| Sun | 21/06/1987 | 31449 | 1S39 1132 Poole - Glasgow Central between Carlisle - Carstairs |
The Railgen archive search menu has an option to search for workings for class 31s (or whichever class you are interested in) for a particular month, which is useful, but no doubt some interesting workings must have slipped under the radar without being recorded. Apart from those two workings, I can't find any other mentions of Carstairs on there between Jan 1985 and Dec 1990
The August 1985 issue of Rail Enthusiast mentions the training of Carlisle crews on class 31s:
We wonder whether the Scottish breakthrough by Class 31s is about to start... the transfer of 31101 and 31118 to Carlisle Kingmoor for crew-training was one of the most interesting alterations from the start of the May [1985] timetable. (Rail Enthusiast - Aug 1985 issue)
18 months later, the same "Traction Talk" column has this to say about 31s working into Scotland from Carlisle:
Visits of class 31s over the border via the West Coast routes are still very much a novelty, although one does occasionally work from Carlisle on nuclear flask traffic [to Fairlie]. As Ayr crews are not trained, the 31 either works back light or stables in Falkland all day before working back to Carlisle on the 6E84 Stranraer - Scunthorpe Speedlink. (Rail Enthusiast - Feb 1987 issue)
The same column has a few mentions of 31s working into Scotland on WCML freight:
31200 (CD) 31130 provided the sight of a double-header class 31 over Beattock on March 19 [1988] when they returned a PW train to Motherwell from Castleton yard [6Z54 07:00 dep] after maintenance. (Rail Enthusiast - Jun 1988 issue)
31432 (IM) was parked at Carstairs on January 11, having failed on an unidentified 3Z40 special working (Rail Enthusiast - Apr 1986 issue)
Class 31s appear with increasing frequency over the western side of Scotland. 31171 (BS) worked a Carlisle - Mossend freight on July 17 [1986], but had to return immediately because Motherwell crews are not passed on 31s.
31122 (KD) is reported to have worked a special freight to Ayr Falkland Junction on the morning of August 7 [1986], and on the 20th 31174 (IM) the 6E84 Stranraer - Scunthorpe Freightliner [Speedlink?] through the town. (Rail Enthusiast - Nov 1986 issue)
Another visit of a 31 to Glasgow Central occurred in June 1988:
31416 (CD) was seen in Glasgow Central station on June 30 [1988] with the high speed track recording coach. (Rail Enthusiast - Oct 1988 issue)
The formation is seen here approaching Preston the previous day as a 1Z25 11:15 Euston - Glasgow:

There's also this mention of 31176 on the Railgen Archive which suggests it may have reached Glasgow on this unlikely working (photo confirmation would be nice!)
| Sat | 14/06/1986 | 31176 | 1S19 1648 Penzance - Glasgow Central DH with 47613 between Worcester Shrub Hill - Glasgow Central Pilot |
And this unusual working from Carlisle to Motherwell:
| Mon | 16/03/1987 | 31259 | 1Z71 1837 Carlisle - Motherwell CONTROL RELIEF |
I'm sure the odd 31 was sent up on a Carlisle to Glasgow via Dumfries service now and again?
31s occasionally visited Dumfries on passenger turns from Carlisle, such as this working:
31428 (CD) and four Mark 1 coaches substituted for a failed DMU on the 0635 Carlisle - Dumfries and 0746 return on January 28 [1988]. (Rail Enthusiast - Apr 1988 issue)
I found one instance (looking at the late 1980s) on the Railgen archive of a 31 working through to Glasgow on the GSW:
Fri 01/07/88
31324 1S50 0808 Carlisle - Glasgow Central
31324 1M03 1313 Glasgow Central - Carlisle
I think this was a regular loco-hauled working, but not for a class 31!
