Given both diagrams off Crewe tomorrow (30/05/2026) are 197s... and 3 sets are at Canton tonight, that's given me a thought.
I'm thinking one of the 3 sets at Canton tonight (67012+HD03, 67020+HD07 & 67025+HD01) will work 1W11 (which is booked a 197 on Saturdays) to Manchester, which'll then replace 197044 on 1V37. 197044 would then join the 197 that does 1W12 upon that arriving into Manchester, forming 1V38... which is booked for 2x 197s between Manchester and Swansea.
That'll at least mean that there will be 3 sets out, as it looks like the Crewe starter/finisher will be 197019 all day. Makes sense if it is, as that way things will be balanced at the end of tomorrow.
Not saying that any of this will happen, though I will be quite surprised if what I suggested above actually happens...
