strengthening and extra shuttles in Manchester at Christmas, are they simply postponing regular overhauls to maximise availability for service? Because when they strengthen the Cumbrian services for the half term hols (around this time of the year) there they always do it by pinching a Manchester unit for a week.
A few years ago when there were complaints about Saturday Mid-Cheshire services being so full that some people were made to wait an hour for the next service Northern said they couldn't possibly use more than 5 x 2 car DMUs for the Mid-Cheshire line, even though there are 7 x 2 car DMUs used at peak times on weekdays. However, more recently 2 of the 5 diagrams on the Mid-Cheshire line on Saturdays have become 4 car instead of 2 car.
The de-strengthened services next week will be:
0741 Rose Hill Manchester
0854 Rose Hill - Manchester
1623 Manchester Marple
1718 Manchester New Mills
1822 Manchester New Mills
I would have thought some of those could still run as 4 car even with a unit down with a diagramming revision for next week. I'm thinking specifically about the pointless 6 car working from Manchester to Buxton at the end of the morning peak and the reverse mid-afternoon. Then in the afternoon the 16:51 Manchester to Buxton service is formed using units which run the 15:02 Chester to Manchester meaning 4 of the 6 carriages that come up from Buxton in the 6 car formation sit at Piccadilly for around 90 minutes doing nothing at a busy time.
