There were six 319 four car sets outside Allerton Depot yesterday morning at about 10am.
At 10am M/F, sixteen Allerton-based 319s are required for service, and this situation has prevailed for close on two years now. More recently, a seventeenth has been needed in the afternoon peak only, in order to work a Liverpool to Preston train which had been cut back from its previous destination of Blackpool.
When the peak turnout became sixteen, the allocation of 319s to Allerton was twenty, and this continued when the seventeenth was required for service. Within the last few months additional units have arrived ready for the Manchester-Bolton-Preston route going electric, the new total was going to be thirty-two, but units have now arrived which hadn't been on the schedule, so whether these are additional, or replacing others, we can't be sure. Anyway, a total of twenty-five 319s have now operated in service from Allerton, although at least one is temporarily out of action, and there may be one or two others which are unavailable for other reasons. However a situation of sixteen units in service, and six parked on public view at Allerton, is perfectly possible.
