Greater Anglia have 24 4-car and 14 3-car 755s, some of which were meant to be for a through service from London Liverpool Street to Lowestoft that now doesn't appear to be happening and maybe an increase in the service from Ipswich to Peterborough.
I have counted up a peak weekday requirement on the existing services for about 26 units, noting that some only work part of the day and swap with other units at Crown Point.
If these are spare and Greater Anglia need to offset lease costs, could the spare 755s be redistributed to East Midlands Railway to run Norwich to Nottingham?
It looks like seven units would be needed for an hourly service Norwich to Nottingham. 33 (or 34) from 38 units seems eminently achievable even for a diesel fleet.
This might allow EMR to avoid needing to obtain the Southern 171s for a while.
