7-car is the longest you'll get these days, the original 9-car ones were reduced to 8 under Midland Mainline AFAIK (to lengthen some 4-car to 5-car), then EMT reduced them to 7 to increase all 4-car to 5-car (this was before the Hull Trains 222s arrived, so these are still 4-car).
I travelled on it a couple of days ago. I noticed some new luggage space in one of the cabinets by the corridor connection, I wonder what was in there before?
Recently travelled on 222005. Is this the only 7-car set in the fleet, or does EMT move carriages around pretty often?
For most of last year EMT were operating a hybrid unit masquerading as 222005 with coaches from 222022 and 222101. (005 is now back to its correct formation).
I presume 222013 and 222101 are currently being refurbished as I haven't seen them in service this year.
Doubt it, I thought 5 and 4 cars we're being done last, with 7 cars first

222001-005 are the 7 cars, then 006-023 I believe are the 5 cars. And 222101-104 are the 4 cars.
Does anyone know the diagram for this unit tomorrow?

It's been said recently that there is little traffic between Nottingham and London (hence more stops on such a short journey), has anyone that's done this route found this to be so? On loading from Nottingham is it really that quiet?
It would seem that if length of trains has been reduced a while ago then there can be no need for trains any longer it would seem. I find it a little odd though. What about Sheffield or are Sheffield trains run in 10car formation?
I have noticed some Nottingham services seem to be booked for a single 4 car unit ( 1130 St Pancras - Nottingham, 1902 Nottingham - St Pancras)
