On a similar subject - did 158s/175s ever work to Clitheroe while it was all FNW?
Whenever I've seen trains on the Clitheroe services , I've never seen anything other than 150/153/156's.
It was odly quite common to see a single 153 on what used to be the 17:12 Clitheroe to Rochdale in FNW days, even though it was obviously a peak-time service, and also the fact that the branch is usually 150's.
156's could sometimes run up to Clitheroe, especially on the diagram which finished with the 21:36 Clitheroe to Buxton train, but 156's seem to be more common over the weekend, for some reason.
I've never ever seen a 142 stroll onto the branch north of Blackburn, but have seen one on a Manchester to Blackburn service before, suggesting that they may not be allowed on the Blackburn-Clitheroe stretch?
When I did the very enjoyable Manchester to Buxton trip earlier this year, I had a nice ex-ATN 156, but don't know how common 150's are- Maybe Gizmogle can tell us?
