I stated clearlyThe 153s were probably the only thing available at Crewe to replace the failed mk4. Better than a cancellation.
Why is it 100% failure? Surely 100% failure would be no mk4s out but as far as I can tell there are 3 out.
TfW would fail to run 5 diagrams on more days than they succeed in running 5 diagrams in 2025
Out of 2 days in 2025:
Day 1: Not planned 5 diagrams because of Crewe work (?), but the Holyhead was a planned substitution so no test of the 5-diagrams = 0 out of 0
Day 2: 153 substituted on the 06:27 ex-Manchester. So not even the reduced set of diagrams covered = 1 day failed out of 1 day assessed.
If you think it is unfair to say that today was a failure of the Mk4s to cover 5 diagrams because the Holyhead was already unable to be a Mk4 then that would be a tenuous defence, but maybe we can reset it to 0 out of 0. Though I think not managing to get either the 06:27 or the 12:30 ex-Manchester as Mk4 means today is rightly chalked down as the first failure of 2025.
1 out of 1 is 100%
