I thought the DfT specified that Nottingham fasts include a Derby
portion that would be split off at Leicester. Surely not a good idea
due to reduced capcity for Nottingham in particular. Is this still
proposed?

AIUI the plan to split at Leicester has been dropped. Instead, a 5th train
will run each hour, a far as Kettering (and possibly Corby). This presumably
means that one of the existing stoppers will be accelerated by omitting some
stops south of Kettering, to be replaced by the 5th train, and will mean
that Market Harborough keeps 2 trains per hour.
